Re: Oldsmobile W27 rear end differential housing
My 1970 olds was ordered with the w-27. During the restoration the expert on this rear end Joe from Texas, restorer and I agreed the differential came with aluminum anodized bolts on the cover. So mine looks like the one in the picture with different bolts. In addition since mine was a California purchased W-30 one of the top fins on the cover was trimmed to allow for the extra fuel line for the California smog. I thought my cover was junk till I found the dealer bulletin on the cover. Huge research required for only one aspect of the restoration, but fun.

Re: Oldsmobile W27 rear end differential housing
The bolts on the one I posted pics of are to be original. However, I would not think that the restorer paid that close of attention to the coating. I have a pre resto-photo I'll try to scan.
Cool info!
