With the exception of the Vicky rear bumper, I have always believed that the front and rear bumpers of 33/34 cars have the same amount of arch before they are mounted, but that the front bumper ends up straighter than the rear when they are mounted. I have seen statements that the rear has more arch than the front before mounting, making them different from each other. Is there a definitive answer to the question, "Does the rear bumper of a 33/34 have more arch than the front bumper before they are mounted"?
