Here are a few more pics First one is a better pic of the shroud top mount bolt. You can see how it's flush to to top of the shroud. I already enlarged the slot/hole as much as possible. For.some reason pic keeps flipping upside down no matter what I do. I even flipped it in the editor and it sill shows upside down Here you can see the white area at bottom of shroud where fan is hitting

Thank you for the pictures. Very enlightening. I am using an original equipment fan and am able to adjust the shroud up and down. The issue I run into is that I can't adjust the shroud down any further. The mounting bolt hits the top of the shroud in the slot shown in your first and fourt pics. There is no where else to go further down. There is more adjustment that could be made to slide the shroud farther down the radiator mounts if there was more room at the top. One other thought I had is that my radiator bracket is bent and seems to be pointing a bit upwards. That could possibly give it another half inch of adjustment. I tried to bend the bracket bit the metal started to crack so I stopped. Do you have any pics of your radiator mount bracket on the car and radiator similar to my 3rd pic above? You can see in that pic how my mount is angled upward on the top of the radiator instead of flush. That could be contributing.

Agreed. I was thinking I would go with a larger single fan mounted to the inside of the radiator nestled inside the stock shroud. Basically you will only see it if you look down inside the shroud. Will function as a puller fan like the original. That will let me keep the stock shroud look which I love and enable me to figure out the stock fan later. Sounding very tempting but still want to try one or two more things on the stock fan to get it to work. Trying really hard to keep everything original but might have to deviate here just to keep things moving. One other question. How long can I run the engine with no fan at all. For now the fan is off and i wanted to do a few short shakedown runs and let it really idle for a good 10 min or so to find any leaks or other issues.

Thanks. Which derale unit did you go with? I was looking them last night. I'm planning to keep the oem shroud bc i like the oem look and just mount a single or double fan setup on the radiator if I go this route. Will check out the PWM controller. Appreciate the info.

Sorry. Bad picture. That is where my shroud is mounted to the radiator but it's upside down in that picture. I used a hex cap head screw so I could push the shroud down as much as possible. The oem bolt head and washer was much larger so this gave me another 1/4 inch of clearance. You can see where I ground out the mounting slot as well to give maximum clearance all the wAy to the top of the underside of the shroud.

A few more

With the fan out I was able to get some decent pictures here. One thought, i noticed my radiator bracket seems to be angled up a bit, which in turn could be raising the fan shroud up higher than it should be. I included a pic of that as well. I could shim it under the mounting bolts, but still seems that even if I shim the bracket the fan clearance at the bottom would still be too minimal. One other note, i even got a second stock fan to test in case my original fan was bent.

Thanks I'll check that one out from CARS but hesitant to buy another shroud and have it not fit again. Maybe could work if I'm able to return it if it doesn't fit. I need to order a few things from them anyways.

Have been struggling getting the oem fan and clutch fan setup to fit my shroud and might just switch to an electric puller cooling fan setup. Is anyone running A good setup they would recommend? What electric fan are you running and how did you mount to stock radiator? What are you using for a thermal switch to kick the fan on? That's always been the challenge when I've added them to cars that don't already have a port on the thermostat or somewhere that can be used. Thanks. Raul

Ed, Its from opgi,. The quality is good and all the mounts seem to be in the right place. Just off in the fitment who could be my shroud or my car. I've tried two other from different sources and similar issues. Ray, I've checked the motor and tranny mounts and they look like they were replaced at some point. At some point in the future I will likely pull the motor and tranny for a rebuild but for now I've let scope creep slow me down for years on this project. I'm getting it back to a driver asap so I can enjoy it with my kids before they are too old. I'm either going to trim the shroud today or put an electric fan in there and come back to the oem fan later. I pulled the fan last night but now I have to drain some coolant and pull the hoses just to get the damn shroud out l.

Thanks! I'll make the mod to the bottom of the shroud and let you all know how it goes. That means I have to take that damn fan and fan clutch off yet again. Grrr but it will be worth it to finally have it done. Thanks everyone for the help.

The fan is just slightly hitting the bottom of the shroud. I will just cut a section of the bottom shroud out and rivet some formed aluminum on there so not too worried about that. Could very well be the mounts causing that. The mounts look to be in good shape from what I can see but how old they are is an unknown to me. I mounted the shroud in the stock location using the stock radiator mount and the 2 brackets at the bottom cross member. The real clearance issue is with top and front of the shroud. If I use the stock fan clutch the fan blades literally can't move at all so that's why I got the shorter fan clutch, which works but moves the fan blades closer to the motor and accessory belt.

Thank you.

Great thanks. Just replied back to your PM. I'll take them.

Thanks I ran it for a few min yesterday and it seemed ok but wasn't sure under hard braking etc if the blades might flex.

I've tried to find one an oem shroud but have never had any luck.

How close to the belt is too close do you guys think? Right now the fan blades are probably about a half inch maybe a little more from the belt.

That angle makes it look a lot farther out than it really is. The fan is positioned nicely in the shroud and a little less than half is sticking out. The problem is if I use a spacer or the original fan clutch, the blades then move closer to the shroud and hit the shroud. Clearly the aftermarket shrouds all fit like crap so trying to make it work. This is the 3rd shroud I've tried. Everything is good on the shroud side but I'm worried the fan blades could hit the belt. Not sure how much those fan blades will flex. Hoping not much because the fan is so heavy and the thick blades, but I guess hope is not a good strategy for me to rely on. This damn shroud and fan setup continues to be my undoing holding me back. i want to get the oem setup right so badly buts it's fighting me so hard. Raul

Does anyone know the correct thread size for the air cleaner stud bolt? Looks like the PO forced a wrong size nut on there and i want to try and chase the threads and put the correct wing nut on there. Thanks.

Hi. Are these bent or damaged in any way. I have a whole front end rebuild kit and getting these would allow me to rebuild these off the car and then just swap them out.

After many iterations, cutting grinding and bending, i finally got the oem cooling fan to work with the aftermarket shroud i put in. To do that I had to use a clutch fan that was a bit shorter which moves the fan closer to the engine. Are my fan blades too close to the accessory belt here? I'm about to give up and put an electric fan in. I really want to keep everything as original as possible but I just can't waste any more time on this. What do you guys think, is this ok or asking for trouble?

That did it! Its alive again!! Been about 4 years since she ran last. Will do a separate update post once I let it run a while. I can tell i need to make a fan adjustment and tweak a few things before I really let it run. Will let you all know how it goes.

I just got from the parts store. I bought 6 feet of 1/4" rubber fuel line and it appears to be the right size. Splicing it in and will let you guys know how it goes.

Sure you're not thinking of the oem metal lines? The ID on the rubber line on there is definitely smaller than the 5/16 runner lines i have and the 5/16 runner lines is pretty loose on the return nipple on the fuel filter. Possible what is on there is not right.

I just used my mighty vac and i only had to squeeze the trigger once and there's fuel right at the filter so looks like the pump was pulling fuel up to close to the filter. I checked the fuel line to the carb and was able to blow through it easily so no obstruction I'm seeing in the carb. Then I checked the rubber return line and it was cracked almost in half about an inch up from the filterl. I think that's the culprit. I was already going to replace that line anyways. Going to splice in a new line just to test it. Just trying to let the engine idle for 5 to 10 min to check for leaks and see how everything is sounding. What size is the return fuel line if anyone knows? Its definitely seems smaller than 5/16.
