1974 Original SD-455 Exhaust Manifolds - Worth?
 

I have a set of original SD-455 exhaust manifolds with original studs, nuts and flanges in very good condition taken off my SD about 20 years ago and wondered what they are worth?

I have no idea and thinking about selling them, so let me know your thoughts, thanks.

Older post but I bought 2 sets last year, one was perfect the other minor repair like what these need and I paid 500 per set which I felt was fair. Mark

My car has 40k on them. I've owned car since new. The right side is cracked. I've heard that will happen. Not trying to say for price ,just to let you know.
