OK I'll be right over. we really don't bag 'em here. I mean we do but there are better places to look for help. Try the search and maybe you can find some bagger guys here or information or both.
Since we are in off topic, I didn't see that, the pre 52 Buick and Cadillacs have tricky with the front shock A-arm, I would venture to say that a MII conversion upFront is the easy way. I have seen it done. but on most of these cars for the rear you can do a 2 link or 4 link set up. The front is just tricky. I would just find an airbag and adapters for the spring and do the outboard shock. old thread idea is similar https://www.jalopyjournal.com/forum/threads/1950-buick-roadmaster-air-ride-build-marilyn.976051/
