PERFECT? What's that?  If they were hand done, a little closer to a better job, but they are assembly line cars. NOTHING was perfect back then. NCRS will verify the fact that if they didn't have the part that was suppose to be there, they used something else. Paint ran and dribbled, equipment was less than precise, laborers had bad days. If you are happy with it, so be it. Enjoy it.

Boy isn't that true? I bought an inside mirror from Wilcox. It was the wrong one. Why? It was black plastic. Mine was silver. My 72 was built in August 1971 and got a leftover 71 mirror.

Suggestion You have two post Edelbrock vs. stock and Flame arestor. There is important information about the air cleaner ex. Element, space between lid and base in the Edelbrock post that you didn't mention in flame post.I checked the members that responded to Edelbrock are not the same has the members that answered flame. Just trying to be helpful.

I forgot to mention that the members that replied to arestor post have 72 Vettes according to there description. I think the members with the 72 vettes can answer the question about air cleaner clearance, element etc. or give you information how theirs are set up. 😬👍

I thought the flame arrestor was just used on the big blocks and the small blocks used the little air filter on the inside of the side of the air cleaner housing.

The flame arrestor I'm talking about is this guy. And yes, my SB has one.

Ah HA!! That makes more sense. I thought you were talking about a large one that fit inside the air filter.
You can certainly clean that little turd with brake cleaner.

I mis-remembered about the flame arrestor.  I thought it was only BBC because that was the one I got when I was running a '65 Rochester FI unit on mine and was using a custom open-element air cleaner cuz the stock mid-year one wouldn't fit. (not to mention insanely expensive)

Anyway I just looked it up in one of my old Chevrolet Parts Catalogs and discovered it was used thru '72.  When they went to the closed air cleaner in '73, they put the crankcase air intake on the outer shell and used a small filter there.  Not sure why the change unless it was somehow emissions related.

Joel?  Have you seen anything about a guy that got a new ECM for his 1981 Shark?  Just wondering.

Flame arrestors are only req'd when crankcase is vented downstream of the air filter to prevent a backfire from igniting the crankcase.
