ive never built a complete frame before.. but i would say your probably going to have to have a little more information that youve given to get ANY sort of helpful response.
Ya wat he said?????????????? What kind of car? I did one for a t bucket years ago ? Like 25. Piece of cake I just made it fit my body. Dave
a friend of mine has built two (one for a '29 roadster pick-up, one for his '31 coupe). he did a real good job with both of them. maybe i can get you some measurments if you're building a coupe. he sold the pick-up.
