12 bolt yoke

[JRSully]

looking for a 12 bolt Yoke for a 70 Nova BB, believe the p/n is 3879208, don't know if 4spd/auto specific, but it is a 4spd application. Might be interested in a new Spicer U joint go with it

Guessing that that you have ruled out the pinion and bearings for the wobble you described?

yoke not moving as a whole, u joint end cap seems to have a very slight wiggle on the yoke side while torqued to spec

I believe the part number 3879208 is for a flange that takes the U bolt clamps to hold the U joint in place which would be wrong for your car.

If your rear is original to your car, it would take flange 3954393 which was later superceded to 3996118. Those flanges have straps that are bolted in place to hold the U joint.

Here is the flange a '70 Nova 12 bolt would take on eBay...

Here is an auction showing the straps and the U bolt differences.....
