I have a 56 buick that needs bumpers rechromed, I like the looks of the 55 caddy dagmars and they look like the should fit. I know they didnt do a lot of platform sharing back then, but is this a easy change? And what do I need? Caddy dagmars on the buick bumper with buick fillers? Any info would be great, I figure if I have to chrome it all might as well do it now.
