Maybe you guys can help me out with this. I bought an original GM yoke and the seller stated that it was off of 69 Camaro 12 bolt rear. I recieved the yoke and it measures 3 5/8" between the tabs that hold the caps on and has 1 1/16" caps. It has a 9210 casting number, but I can't identify it.

Would I be correct to say this is a 1330 series yoke? I thought the 1310s were used on Camaro 12 bolts. My drive shaft yoke measures 3 3/16" with 1 1/16" caps. What applications were the 1330s installed on? Thanks

think what you need is a 400 to 350 conversion joint but not 100 percent sure. gear head will know better

Yes, that is probably a 1330 yoke. They were used on some of the heavy duty 12 bolt rear ends.

Thanks for your help. After searching the internet half the day, I found out what it is. The part number is 3879208 from a 68-72 LS5-LS6 12 bolt Chevelle. If anyone is interested in it, let me know. Thanks again
