What are the correct exhaust manifold numbers for a 72 350 4x4 with a/c? Thanks!

Are you looking for correct as in I want a concours restoration? Or are you looking for what stock manifolds will work with my 350 with AC?

I had a pair on my 4x4 when I bought it. They were on a 350 at that time. They have been through one engine change (to a 383), a tranny/t-case swap (3-speed manual/205 to th350/205), non-AC to stock AC mod, and a bent to crap single exhaust to LMC dual exhaust "kit".

In none of the above configurations have I had one issue with the fit, with clearance, or with any leaking. Both are marked "RH" and appear to have the same part number.

I also have never bothered to write down LH or RH on them. I just bolt them on if I have them off for some reason.

If you're curious that is that Eastwoods exhaust manifold paint on them. Good stuff.

I don't work for Eastwoods or LMC

From the GM parts catalog. Just remember these are service replacement numbers and may differ from the production p/n used during inital assembly.

mrein3, which paint did you get, the silver? Thanks Randy

The can says factory gray and cast iron color. Part #34105Z. I can't believe my bride didn't toss is yet.
I'm VERY happy with how it has held up.

So it doesn't matter if both are RH? Does it fit the same?
