70 Chevelle 3.31 12 bolt posi
 

I have a 70 Chevelle 3.31 12 bolt posi. It is coded CCW for 3.31. It was out of a 70 SS Chevelle that was parted out. No welds or repairs. Good used unit that has new seals installed and is painted black. No brake hardware. $900 obo must pick up I really don't want to ship this unit.
Thanks SYC,
Matt

That's an open rearend originally,not a posi.Did you or someone else modify it?
I have a friend looking for a CW.What's the casting & assembly date?

Re: 70 Chevelle 3.31 12 bolt posi
 

Yes I know that this rear was originally coded for an open 3.31. The posi unit was in it already when I opened it up. It is a GM 3 series posi unit. I cannot read the casting date on the housing but the assembly stamp is 0812K.
Thanks,
Matt

There is a 1970 Chevelle for sale on this site and ebay that has a CCW rear end but it appears to have a E stamped on it. Is this still a factory posi?

I will have this rear at Corvettes at Carlisle this coming weekend. My space number is L88... easiest space to remember at that show!

Thanks SYC,
