Model A Coupster

[40FordDeluxe]

Ok guys, do you remember when I started the thread about wanting to build a traditional type rod with an unusual powertrain? Well it's going to come to some sort of reality.

I picked this up and need some guidance. I think this is a 28 or 29 sport coupe with the roof cut off. I know it is missing all inner structure, but it isn't super rusty and I feel it is a really good start. The guy I got it from said it was a coupe cut down to a roadster and was a complete hot rod at one time. He said the guy he got it from had it as yard art but moved and had no room for it. To me the quarters appear to be a roadster, but the doors and cowl are from a coupe. What do you guys think? I also need your input on the inner structure. Should I purchase new sub frame for the body or just build it to suit my build? I will be building the frame myself as I will need to lengthen the front area. I'm contemplating buying new doors for a roadster, as these doors's body lines aren't the same. I plan to purchase a new deck lid and rear panel that goes below it. I'm kind of thinking of doing a Highboy style but not real sure on that yet. Here are some mock up pics of what I have to start with.
