The subrails on my '31 coupe rotted long ago and were replaced with some roughly hewn angle iron. I need to fix that but since the car is channeled over a wide frame, I can't bring myself to buy and chop up a $350 set of new subrails. The most complex and visible shape, of course, is in the door openings. Has anyone come up with a novel method of fabricating their own? I searched but couldn't find. I'm thinking brake press sheet with notch/bend/weld/grind to get the correct curvature. Pics are appreciated.
