What model diffs are they? Never seen anything like that rear one.

It is a Spicer 402 read diff. It is the SPL170 bearing and heavy driveshaft that makes it hard to find the right yokes. That model yoke (the 161) is obsolete with no replacements avail.

I purchased a 221 yoke and precision-machined down the back of it by 0.380" + under-cut the back end of the splines it to make it fit.
