Small update, more cleaning while waiting on parts to get delivered. The back of the wheels were black instead of gold so I gave them a good scrub with Sonax and it came right off.
The transmission was covered in filth so my brother and I spent a few hours scrubbing before we got tired of it. I gave dry ice blasting a try and it went alright. It didn’t get the really nasty parts but got most everything else.
Currently working on replacing the heater box studs that were broken off before I pull new fuel and brake lines through the tunnel.
