I have a 9210 yoke that fits a 12 bolt. Has been blasted and has no dings or marks of any kind. Very nice shape.
Uses straps and screws to attach (not u-bolts).
It uses a 1330 ujoint which is 3.625 or thereabouts from end to end.
I believe all the Camaros, Chevelles and Novas with 12 bolts used the 1310 u-joint.
This guy is selling an nos one on ebay and says it fits first gen Camaros with the 1330 u-joint:

Z/28's all used the 1310 u-joint, correct?
Then I got to thinking (dangerous) that maybe the th400 cars used different u-joints.
So.. maybe this is for a 12 bolt in a th400 car.
Anyone know?
