What's the Stock U-Joint Size for 4th Gens?
Looking for confirmation on the stock u-joint size for 4th Gen Camaros ... Where the rear of the driveshaft mates to the 10 bolt rear ...
Is it a 1310 or 1330 ???
I've been told by a driveshaft specialist that a driveshaft with 1330 u-joint will bolt up to the 4th Gen 10 Bolt with no modifications to the 10 bolt yoke ... Is this true?
Thanks ...

Ok ... I finally found that the stock ujoint is called a Saginaw 3R or somtimes referred to as S44 ...
The dimensions of this ujoint are very similar, if not the same, to the 1330 ujoint ... The 1330 measures approx. 3 5/8" wide with a face diameter of approx. 1 1/8" ... I measured an old stock steel shaft and got approx. 3 5/8" wide and a face diameter of approx. 1 1/8" ... So I guess these are pretty much the same except with how they are held in place ... The Saginaw 3R uses a C clip to hold the u-joints within the yoke and the 1330 series uses injected plastic to hold the u-joints with the yoke ...

they are all 3R or S44 joints.......
the 1310 or 1330 will not bolt up to the 3R pinion yoke....
specs of the 3R/S44 joint: lock up=2.556 (inside) bearing dia.=1.125"
specs of the 1310 joint: lock up=3.219 (outside) bearing dia.=1.063"
specs of the 1330 joint: lock up=3.622 (outside) bearing dia.=1.063"

the 3R and 1330 have different bearing cap diameters.....not by much, but they are different
1.125" vs. 1.063"
I would not want to run a 1.063" dia. bearing cap in a yoke calling for a 1.125" dia bearing cap.
