Hi & welcome if you do your ride in a manner that is in line with what we do here. I only mention this because in your introduction post you mentioned a build in a manner that does not fit & is not allowed here. Good luck, Jimmie
If you are gonna do a 4 door do it right, here is my sons car he clocked a few thousand miles on it we made it safe, dependable and cool. In line 6 from a 1960 original from there on.
