nos or reproduction

[Darren P.]

I have found a set of midyear sidepipes and covers and also a 67 glovebox door. what is the best way to tell if they are nos or repro"s. the exhaust stuff has no boxes but the door is in a old box marked 1975, thanks for your help

Darren,
On my original 67 small block 2" side pipes the GM part numbers are stamped into the pipe just down from the exhaust manifold end. My numbers are 3877215 and 3877216 (left and right). It also has "GM W" stamped nearby which I have been told signifies a GM part made by Walker Manufacturing, the original supplier of exhaust systems.
