68 Skylark Convert 12 Bolt

[BIGBLOCBOB]

I Have A 68 Skylark With A 8.875 12 Bolt Rear With An Open Axle I Am Looking To Put A Posi In It
Will Chevy Truck Drop Ins Work In This Axle??
Or Is There Anything Esle I Can Use Other Then Buying A New One
Thanks

Assuming it is a Canadian produced car then it would be the same as the Chevy 12 bolt CAR rear. Parts are readily available.

The Chevy truck 12 bolt differential can be adapted to the car housing, but I do not recommend it. The truck differentials are weaker than the car differentials, and it is too much trouble to make it work. Just get an Eaton for the car 12 bolt. I also don't recommend the Auburn. You will have to get the correct series for the gear ratio that you are running. Send me an email if you need more information. biggearhead@bellsouth.net
