Hi folks, I have a 1950 4-dr Styleline Deluxe bought new by my grandpa, just had the bumpers rechromed and want to buy nice shiny new bumper bolts. Two questions: first, do the front and rear bumpers have different bolts? I'm not sure if the ones we took off my car are original but the front ones are slightly longer and the dome head is slightly higher (more rounded) than the bolts on the rear. Second question: where's the best place to order/buy new bolts? Looking at the usual sites (Chevs of the 40s, The Filling Station, etc.) seems like the selection is all over the place, some have really high domes, the heads of some look to be bigger in diameter than the ones we took off my car, etc. Any bumper bolt experts out there?  Thanks! Joe
