i found this in the pumpkin dif. of a rearend i bought some time ago.
The rear end is a disk break posi out of a 89 iroc. i was told the piece of metal is a clutch? All the teath on the gears are intact. Where can i buy this piece?
Any help identifying the rear end would be awesome also. Thank you very much

 

The picture is out of focus, so it's hard to tell for sure. It looks like it might be part of a clutch disc from a Governor Lock differential. It could also be one of the differential shims.


If it's a piece of a clutch disc from a Governor Lock then don't bother trying to replace it. Just replace the whole differential. The Gov Lock is not a good differential for a performance car. They break a lot. Get a new Eaton Posi, Yukon Dura Grip or a Power Trax Grip Lok.
