the pics are up on the thread [how bad was your car when started] of ther roaster from the woods here are them. and there are other stuff
That back half doesnt look to be from a roadster, looks like maybe a wood supported top was on there, or maybe a sport coupe.
theres a nice pic of a 29 buick dash here: www.29buick.com matches perfectly, although its on a closed car. it also has the little door on the side of the cowl.
Most of the 20's Chryslers didn't have that raised bodyline like that car has. Also, the golf doors on most of them were square. That body has a golf door with a halfmoon cut out for the rear fender which should help ID it.
