So I want to fill in my roof but I would like to know what modern car I could use for a donor roof. I live up in SE Michigan so there are really no oldies in junk yards to cut out. What have you guys used? I'm building a Henry Ford 31 coupe on 32 rails, 40 cross member, 9", 55 caddy 331 with dual quads, T5, 3 inch chop, 32 grill, louvered hood, steelies, pie crust big and littles, 35 dash, SS floors, pleated interior, cross steer. What am I doing wrong with the build if you want to comment. sure no one wants to see another 31 build.
