Pulled the motor and trans out and removed all the vacuum and brake lines. Need to weld on a new plate at the back where someone hacked a trailer hitch on. The frame is surprisingly still pretty square based off a few quick measurements, especially at the cab mounts.
Time to start grinding off most of the rust in preparation for paint. I'm think of Eastwood Rust Encapsulator Platinum and Eastwood Chassis Black. Anyone used these products before? I would also use it on all the suspension and steering parts.
