Where can I get parts for a 1939 Studebaker Champion?

Well my brother and I are restoring a 1939 Studebaker G Champion Sedan with suicide doors. We need tie rod ends, the steering rods they thread to, a frame bushings/ control arms, front and rear shocks, and possibly leaf springs. I live in the Denver area if you know of any local places. My brother says he NEEDS to know if the part is exactly perfect. I showed him some tie rod ends on the internet for the '39 Champion and he said he wasn't sure if any were correct. So only answer if you know of a place I can go to to find parts, or if the ones on the internet will for sure fit this car.
