I don't think that would be too hard to do. I have an old compressor that came from some kind of vehicle air suspension in my parts stash, had it sitting there for several years. all I would need are a couple of leveling valves and some tiny air line tubing to tie into.
there were a lot of older sedans that used air ride systems, I'll have to search amazon and other online sources for some parts to see what I can come up with on a cheap budget. put that compressor up to some actual use!
Heck, if they make air shocks for the front end that might make a world of a difference if I go to a lighter spring like the 3/4 ton ones!
