12 Bolt Diff COVER ?????

[CamarosRus]

I have what I believe is a USED, GM/OEM No Notch 12 Bolt Cover.........

I cant see any stampings or ID markings

Someone suggested it was a truck cover.........

What do I have and what is it correct for ?????

That is not a truck cover. It's a Chevy car 12 bolt cover.

How is the truck cover different?

68- 69 Chevelle for starters.

No conclusions yet..............Is there a list somewhere that states all the different 12 bolt diffs that had a NO Notch Cover.......like my above pics ????

I think the 12 bolt covers with the notch are correct for 1970

How is the truck cover different?
Completely different shape.

Early assembled 1970 Chevelles received the no notch cover.Later + assemblies got the newly designed brake line clip "notch".

So the notch was in all the OEM covers from 62 to 74?

Ooops 64 to 72

The car 12 bolt wasn't used until '65. '64 had the 8.2 10 bolt, but axle splines in '64 were a little different from '65 and later.

No, that is just a shape representative cover from a full size passenger car.

This rear was taken out of one of her 68 converts in 1974.
I put it back in after adding a 67 dated posi unit.

The cover is not notched.
Same as the other 68- 69 Chevelles here.
Second pic is the car.
She is second owner of it also.
