NOS exhaust manifold I.D. - 01/30/10 05:39 PM

I was looking through our old parts bin here at the dealership. We are cleaning out one of the old rooms. I found a new old stock exhaust manifold. It is for the right side of the engine. The casting number is 3751068-10. It is dated 3-1-1973. It also looks like it was built on the night shift as the arrow points to the n and not the d on the casting. Anyone here know what it goes to? Thanks, Jason

If that goes on the right side.... The exhaust would exit towards the front of the K-member by the radiator...It's the LH or Driver side...

The number on the part is the casting number. The part number is often 1 number higher.
