12 Bolt "O" type rear cover - Original GM and nice
EDIT: SOLD PENDING PAYMENT
Here's a rear diff cover for a "O" type Oldsmobile 12 bolt rear diff. The outside surface was in remarkably nice condition but the inside was pitted. It had been pulled off a rear diff and left outside by someone.....maybe they used it as a birdbath...who knows? Anyway, I got rid of the pitting on the inside of the cover and it's now clean on the inside. Again, the outside was in very nice condition with only a few small gouges, etc.
It's been beadblasted to bare clean metal and primed with catalyzed epoxy primer. A light cleaning with wax and grease remover and very light scuffing of the epoxy is all that will be required before putting whatever final paint on it you choose.
The stampings on the upper part of the outside are super nice......"TOP" and a "M" inside of a circle. Overall it's a very nice piece.
The inside will be coated with Boeshield since it's bare steel and that can be wiped off prior to installation.
