29 sport coupe to roadster question

Found a clean 29 complete sport coupe body. I own a 29 rpu. Are the body lines and backhalfs from the door line back of a coupster different than a roadster? I've looked at a bunch of pics but it's hard to tell online. Ive been searching for a roadster back half and I'm coming up short.

Probably not gonna match up but it's worth some advice

i think the sport coupe has a shorter deck lid

 

Bodylines are similiar. Quarter panels are longer on the roadster. doors are shorter. The distance between the decklid to the back of the seat is greater on a roadster compared to the coupster. The car in my avatar was a sport coupe at one time.

 

thank you for the reply that answers my question the search continues

 

If done right a coupster can look pretty good. Amazing how much more room there is in a coupster compared to a real roadster

 

I'd just build a sport coupe.... way cooler than a coupster

Deck lids are the same its the panel above the deck lid that is longer as well as the actual quarter panels
