Nice treasure trove of rare parts. I didn't know the valve cover bolts were unique. Thanks for pointing that out.

Yes, the 1971 and 1972 HO engines used a specific valve cover bolt, they are 3/32-1/8th longer and there is only one foundry marking, the NL. I have seen NL short valve cover bolts as well and D's and E's..but the HO ones were specifically NL's. Those were also used on RAIV's and I have seen full sets go for >$100 all day long on Ebay... I bought a box of left over bolts/clips on Ebay a year or so ago for something like $35 which had 7 of the HO valve cover bolts... Steve, if you ever plan on buying another HO...I would definately keep those bolts.. the A/C rear bracket is repo'd by Sonic,and a damn good one I might say, but that NL valve cover bolt is a hard one. I get calls at least 3-4 times a year looking for a set of those... If you ever need a set, I guarantee you... they will be next to impossible to find... I think that was the best part you got...way to go !!

Thanks to Norwood, I have the correct shaker rivets.



My bodyman was very familiar with these types of rivets since he does a lot of Corvette work and they use a similar rivet, so he got the honor of installing them.

First step was drilling out the hole in the repaired fiberglass shaker lid:





The rivet mandrels:







The shaker is then set on top of the rivet and mandrel and the upper mandrel is gently tapped.

As the rivet is being supported by the lower mandrel and not by the fiberglass, it prevents any damage to the surrounding fiberglass.
