U joint at drive shaft/ rear differential

[5akman]

Spent an hour today at Napa trying to find the correct u joint for my 1988 K5/5.7/700r4/steel driveline. One set of caps has a 1.06 diameter and the other set are 1.125. At the drive shaft yoke, the snap rings on the joints are external. Anyone have the part number for this joint as napa can't seem to figure it out.......

That looks like it will do the trick, thanks for the reference!

Turns out its a 1310 to 1330 Big Cap unit. Looks like someone re-did the end of the driveshaft and put a Ford yoke on it hence the mis matched u joint.
