I have a 1950 International L-122 pickup with badly scored front brake drums. These are the 6 lug type. Can anyone tell me the maximum diameter that would govern having them turned? Thanks.

Thanks very much. Now I know what to look for.

Could someone provide me with the correct Anco or Trico part numbers for 1939 Hudson Pacemaker windshield wiper arms, or at least a description of the type and size? Thanks very much.

Thanks Joe. Read the thread two or three time. Reminds me of an ole Blues singer.....Muddy Waters.

I have a 1939 Hudson Pacemaker. A previous owner has the electrical all screwed up, mainly the lights. Today, I finally got around to trying to figure out what he did and how best to correct. In the process, I discovered that the battery is connected with negative ground. My shop manual is not specific for 1939, but previous years of Hudsons show positive ground. The car starts and runs fine. What should I do? I want the car to be as original as possible, but also subscribe to "If it ain't broke, don't fix it." Thanks

Looking for the internal parts for a 1935 Ford headlight. Don't need the whole bucket, just reflector with socket and pigtail. Used or repro ok. Thanks.

I'm looking for the gas pedal assembly that bolts to the floor board for a 1950 Plymouth coupe. Thanks

Looking for the accelerator rod that attaches to the accelerator pedal for a 1938 Pontiac 6-cylinder. Would buy entire linkage assembly if necessary. In lieu of the actual part, would greatly appreciate a photo, drawing, or sketch of same.

When I push the starter pedal on my 1937 Plymouth pickup, it goes in partway and then stops. The lever under the hood doesn't get far enough to hit the starter button on the starter. It seems that the gear on the starter is not meshing with the flywheel and just jams I've tried spinning the starter to get the gear in a different position and have cranked the engine by hand to get the flywheel in a different position, but nothing seems to work. Anyone have any ideas? Thanks.

Found this great video which explains everything.

I have a 1950 IH L-122 pickup with a leaking rear brake cylinder. Took the wheel off, but can't figure out how to get the drum off. Do I have to pull the whole axle out first? Photo attached. Really need some help here. Thanks.

This question actually applies to any vintage car converted to radial tires, but it's my '41 Olds that prompted the question. What tire pressure should I use? The recommended pressure in the owner's manual is obviously for the old bias ply, tube-type tire, but what do you do if it's been converted (by previous owner) to radials with tubes? Thanks

I have to replace one of the lines to the oil filter in my stock '37 Desoto Business Coupe. The existing lines are 3/16". Is this adequate, or while I'm at it should I increase the size? Thanks

PM sent.

Here are two photos, front and back.

How can I determine if I have authentically correct Buick 15" wheels?

I have a 1938 Buick Special that has 15" wheels. The tires are cheap Chinese radials that I'd like to replace. From what I understand, the '38 Specials had 16" wheels. Is it a problem to run the 15"? Don't know what to do here. Thanks

I suspect that I have a blown head gasket in my '51 Chevy pickup. Before I do something drastic, I was wondering if anyone has any experience with these additives to the coolant system that are supposed to fix blown gaskets. PLEASE, before this goes miles off topic, just interested in an answer to the basic question: does anyone have any experience with additives to the coolant system (such as Bars, K&W, Blue Devil, etc) that supposedly seal blown head gaskets? Thanks

No, my measurement wasn't fooling me: I was fooling myself. Guess who failed to zero his electronic caliper before measuring?🥵 Plugs measure about 17.8mm which is close enough to 18 for me. So, I'm satisfied I have a '38 Buick with a '37 engine. Just wish I knew the history. Why would you install an engine from an older car? Guess that's part of the fun having these old relics around. You never know what secrets they are keeping.

The current plugs are Champion D 16. It's the 17mm thread that has me puzzled. It's a 1937 engine number, but 37's were supposed to have 18mm plugs. Here's a photo. Am I measuring wrong?

Here's the front end.

I recently acquired a 1938 Buick Series 40 Special Business Coupe. It took some research, but based on postings on AACA and some other sources, I’m reasonably sure that this is truly a ’38 Special Business Coupe. The firewall plate info and the frame serial numbers all seem to agree. The vehicle has coil springs in the rear, the only firm difference I could find between a ’37 and a ’38. My problem comes with the engine. An original ’38 Buick shop manual says the plugs should be 14mm and require a 13/16th socket. My plugs take a ¾” socket and are 17mm. After a pretty lengthy search, I finally found the engine serial number. It is for a 1937 engine. OK, no big deal. I know that using parts from the previous year was common place, but further research indicated that the original 1937 plugs were 18mm, not 17mm. So, I wonder what I have? You would think that if in fact GM used ’37 Buick engines in ’38 vehicles, there would be some reference in the shop manual. If a previous owner swapped engines, why the difference in plug thread size? Guess it could be both a different engine and a different head, but how could I determine that? As long as I find the correct plugs and get this thing running, it’s no big deal, but I will always be wondering what I have when the need comes to replace other parts. Comments appreciated. Thanks.+

The ban on internal combustion engines is progressing around the world. Some places are even banning fossil fueled chain saws and lawnmowers What's going to happen to vintage car owners? Will the value of our cars plummet? Will we be able to find fuel at an affordable price? Will it even be legal to drive them?

I need a spark plug wrench or socket for a 1938 Buick with straight 8 engine. All mu sockets are too big to fit into the spark plug recess. Thanks

Sorry, I thought this was the antique "automobile" club. 1950 International L-122 pickup.
