The bumper thing...wow. How 'bout a rationalization? Who would put their 38 street rod in harms way? Another one...if someone hits you, they're gonna bend somethin, bumper or not, round or square or OEM. Now if I was going to fab a custom bumper, I'd steal a page from the designers of the 34 Cadillac and LaSalle. Anyone ever noticed or even seen one? We called them Bi-Plane bumpers. They consisted of a top and bottom section of 1/2 oval steel that followed the contour of the front end and each was separated by a round pointed "carrier" to attatch to the frame. 2 carriers front and rear. Today, you can purchase "aero tubing" used in race car construction to do a modern rendition. Any round mat'l could be used for carriers/mounts. And yeah...I'm an old gray bastid myself. Seen a lot and plan to see and do a lot more. When you think about it, most street rods don't even have bumpers.
