There were big block cars that used the smaller u-joints.

There were also small block cars that had the small U-joint in front & the large one in back.

If you are replacing the u joints in your 50 year old driveshaft..... now may be a good time to upgrade to a nice new, non rusty ticking timebomb.

  Agreed, this shaft was made when the car was upgraded to a 4spd. from a 904. It was run a couple of years then stored inside. Having said that this one had the 2 sized joint I used for the large yoke I tried which HOWLED so I am putting the original 2:76 back in.
