I have lurked a bit and found you guys have the best info I can really use. I have a 30 Model A with a 427 and a 38 Chevy coupe tubbed. I am building a 23 Hupmobile right now and am making it a roadster pickup. It was a touring style 4 door pheaton. When I got it all that was left is the cowl forward and the frame. Its a parallel leaf spring front and i would like to keep it that way. I just hope I can get it low enough. If not I might go with a quarter ellepticle style. I got a modified T tub and a Model A bed and it all fits the frame really good. The Hup has a real long cowl so I will have lots of leg room. I got a folding top from something and i will modify it to fit the Hup.
Thats my buddies I was putting together for him, put a drivetrain in and lowered it, It needs some work but made it to Viva!
