Model A Roadster and Sport Coupe Sub Frame Diffrences

Hello, need some help. According to my book, the model a sport coupe and roadster frame rails are the same length, but the roadster cross pieces are wider than a sport coupe. Can this be confirmed? Macs and brookeville market sub frame channels for the coupe and roadster but nothing exclusive to the sport coupe.

Last question, when you have the car torn down to the subframe and start replacing the whole channel and/or cross pieces do you need a jig, or can you just be careful and duplicate the holes one by one?

 

sport coupe and coupe are the same
tk

 

only diff in coupe and sport coupe is the top, body frame same

 

Thank you for the information. I know the roadster frame is wider than the coupe. I etimate about 4 inches, is this correct?

 

Frame and sub-frame should be the same for coupes and sport coupes. Period

 

search for subframe theres lots that have the meaurments on here. That how I got mine for my roadster.
