  1. The only way I know to remove the brake drum is to remove the front hub bearing assembly and the drum will come right off the spindle. You don’t mess with the rivits.
  2. Just wanted to update anyone that's interested. I tried several times, after removing pin on splines to see if all vibrations would be eliminated moving the to the factory spec. location. Unfortunetly, the way my shaft was welded, the spline spacing was about 43 degrees and 27 degrees. (I couldn't get it near the 33 or 37 degrees.) Both of which enhanced vibrations in the 40-45mph area and 60mph on up. So I ended up putting it back at 0 degrees and my vibrations went away. Except for above 70mph which isn't really that bad. This is on a gear vendors, overdrived 64 riviera with a shortened driveshaft.
  3. I will see if that is possible. Got to clean it up first to see what’s what.
  4. If you look real close at the 12 o’clock position between the splines, there is a pin, which I intend to grind out.
  5. Driveshaft your commenting on runs smooth till 70mph. I'm thinking if I phase it right it will work perfect.
  6. I just looked at an earlier post by telriv which answers my question. Looks like I have to do some grinding.
  7. Does someone have a picture of a factory 64 riv. driveshaft so I can compare. My yoke could have been welded on wrong.
  8. Looks like a 64 goes on at 0 degrees and you can’t change it.
  9. I don’t think phasing for the 64 riv driveshaft is required or is possible, because of the 2 cv joints. 4700 series is the riviera. Picture below is the 64 service book which doesn’t mention 4700 series. Maybe I will do it anyway to see what happens.
  10. Telriv, MAJOR mods are needed to add a gearvendors. Trans tunnel was raised an inch which requires cutting an inch out of the shifter bracket so the console fits right. Also frame was gusseted on the outside before removing part of the inside of the frame to make room for the overdrive. Lots of pictures on one of my earlier posts. My car is a daily driver and I would not attempt it on a nice Riviera.
  11. Interesting information on the shuddering cure. I knew I had to get my trans mount as high as I could go since I was adding another 18” to the stock location of the yoke. And since the slope of the stock engine Tranny combo trends downward, I shimmed the trans as high as I could to get the stock angle. And I was sure I could get close since I moved the tranny tunnel an inch higher. Here’s a pic of the driveshaft
  12. Since I caught this post kind of late I would like to add my experience. I installed a Gear Vendors overdrive behind the turbo 400 in my 64 riveria. Stock, this car comes with the yoke in the tranny, going to a carrier bearing then the shaft with the two CV joints. I had no vibrations above 5 mph. but there was a shudder below 5mph under heavy acceleration. After 3 years of living with this I found this was also a problem with Tacoma 4x4's and the solution was to lower the carrier bearing. Very hard to do in a Riviera. So last year or two, I did it. It required cutting the carrier pedestal (for lack of a better word) out of the frame and lowering it. Then I used body shims (currently 1/8") to slowly raise the carrier bearing to where I was just getting a barely noticeable vibration at WOT below 5mph. Moving it there seemed to add slight vibration above 70 mph where I didn't have it before, which I can tolerate. I guess to sum things up, I would think the double CV's would alleviate a lot of your problems as my transmission assembly is quite a bit longer than your 700r4 and I'm not having any issues to speak of. And the Overdrive is real nice. I will post a pic. of the drive shaft today as I currently have it out for its annual lube.
