I've been itching for a "new" car. I found a 1958 Buick Special Riviera (46R). My 66 chevy isn't old enough for me. I stumbled across what I found out to be a decently "rare" car, that's not too crazy low in production numbers. I know very to little about the car, but it's going to need a lot. Mostly mechanical and 1.5ft rusted out frame section. We unloaded it last night (6/25/20), so there are still lots of unknowns. I'm the second owner. I was told it is all original. I almost want to rip out the frame (it's rusted out near the rear springs) and drivetrain for a smallblock or something common and easy. Part of me feels like it'd be ruining an unmolested car. A "rarer" one at that...1 of 34,903 cars. In reality, a more modern drivetrain would be better. Frame, engine, rear end, etc etc. SO, I will be needing lots of guidance. It anyone has any forum posts or resources on a frame swap? let me know! Oh..and it's pink (lucite paint). I'll attach the body tag, I got most decoded, but I have no idea what the "K" is for on the "trim" section of the body tag.
