1931 Model A Coupe to Roadster with 29 back half

Hello folks, I recently purchased a 30/31 model a coupe cowl with a variety of mismatched doors and a 28/29 roadster back half. I have a drivers side door that looks to be correct for a 30/31 coupe and I was wondering if anyone might have a p***enger door for a 30/31 coupe they would part with.

Also, if anyone would know where I can find a sub rail and body blue print for a 30/31 coupe, that would be helpful. I've looked around on the net quite a bit and all I can find are some sketches or pictures someone has added notes to.

Any help would be greatly appreciated.
