I can`t decide whether to rechrome my bumpers or buy some I spotted on craigslist. The seller says they are 70-74 and all driver quality he has a few different ones in a pic for $50 each. The price is right as long as I can find a pair for my car once I see them in person.Are there any differences to look out for? I don`t want to get bumpers that don`t fit right. My front bumper has a slight tweak in it and damage in one of the bumper jack slots plus the chrome is bad on both bumpers. I assume easy fix`s for a shop before re-croming. Will my 72 bumperettes in the rear fit correctly on a the bumper from a different year?
