Question about nos parts

[Tim_Rivette]

Hi guys.

I am new member to this site but have been reading it for years. Have a couple of questions if anyone can help guide me for purchasing some nos parts for a 69 ss 396 numbers matching car I just purchased. It needs a repaint and while taking it apart found out it needs a core support and bumpers. I found a person in my area that has a ton of nos Camaro parts but wants my to make him a offer on the parts . Can someone give me a idea of where to start on a offer for a nos front, rear bumper and a nos core support.
Thanks in advance
Tim
