12 Bolt Axle GM issue Pinion Yoke

[RPOZ11]

12 Bolt GM issue Pinion Yoke.
In this discussion, this inquiry is directed to GM Camaro 1967-1969 (1970) 12 Bolt housings.

Im starting on my 12 Bolt rear axle rebuild.
I am obtaining the parts for it to get it completed and ready for install when the coupe shell comes back from body/paint.

Question:
Is there anything to know about these Pinion Yokes?
I have to buy one as I need one for mine.

12 Bolt vs. 10 Bolt GM issue Pinion Yokes:
Are they the same or are they different?
I was not sure if the 10 & 12 Bolt Pinions had the same thread spline count.

10 and 12 are different but 12 bolt car and truck are the same. most fit smaller 1310 u-joints and use outer clips. there are some for the 1350 joint but seem hard to find some list as a 70 chevelle 12 bolt BB yoke. Aftermarket make some h/d yokes if you looking for original look for truck 12 bolt yokes.
