I figured I'd buy from a FABO sponsor, so I called...

So, did anybody haopen to check Tri-City?? They have a lot of the more common bumpers in stock and are probably the best price going as well, especially for the quality! As mentioned above, I took my neighbors bumpers to the Nats to drop off for rechroming! They're from a 64 GTO, very large and hard to find in any condition! They were straight but needed stripped and rechromed! $550 a piece, which is a great price considering their size! Jus sayin!!!
Tri-City offers 63-76 Dart bumpers front and rear re-chromed for $355 each if you send in a core, or $445 each with no core. Sometimes they have the cores or already plated bumpers ready to roll in stock, and sometimes you need to send in yours for re-chroming.
