U-joint Information

Well I seem to be in need of new universal joints for my P6B 3500S with 5 speed trans conversion. Somewhere on this forum I think I remember someone saying that Chevrolet truck U-joints will work for our cars, but, I can't find the post. Does anyone know if this is correct and, if so, what the part number is or year and model of the truck? Any tips of info are greatly appreciated.
 
Hi Gary,
Have you tried the usual sources for P6 spares. It is not too long ago that I bought New UJ's from Wins.
regards, Barten
 
Thanks Barten for the quick reply. I found new ones at Wadham's, however, they show two different sizes and I am not sure which is correct. Needless to say if I could find the Chevy conversion ones that would make things much simpler as they could be sourced locally and the same day and probably for less money. I'll check Wins just for fun and see how much they are.

Prop UJs are smaller than driveshaft UJs. AFAIK all propshafts use the same joints. (And driveshafts come to that).
 
I finished putting in the new prop shaft U-joints and the result is better than expected. I not only had the clunking going on, but, kind of a 'hamster wheel' screeching I wasn't sure the u-joints would take care of. Happily, all is well and the car really feels transformed. Thanks harveyp6 for setting me straight on the right u-joint. Looking forward to a spirited drive this week-end.
 
Barten, you are so right. The collateral effects from fixing this has also cured a shift linkage issue I was having going from 4th to 5th and 5th back to 4th. Occasionally it was reluctant to go smoothly into gear and I guess the loose u-joints were jerking the trans around a little which upset the linkage alignment. It really does drive beautifully and the reason I bought the car in the first place.
 
Good result
Replacing U /J's is on my to do list. How about putting up a link to the joints ? Will be helpful to others.
A link to the halfshaft joints will complete the picture :)
