they make after market repros that are pretty nice if you have the bumper pad and bumperetts from an old one. i can get you info if you want.
there is a place called action crash that has the chrome part listed for $160 and the reinforcement listed for $79. i could get it cheaper from them but then id have to ship them from cleveland. they have a website listed as www.actioncrash.com but im not sure if they sell directly to the public.dan
