Identifying an original 1967 air cleaner wing nut

It was a one point deduction. And I should have posted its within .001 of a inch of that drawing

Keith, just my two cents here - but your wing nut is not configured like originals. Please note the width between the ears on your wing nut versus the one Wayne posted a picture of. The two nuts are configured quite differently. Also note the inner angle of ears. The angle of the inner part of your ears are almost vertical, whereas the one Wayne posted a pic of are angled out, and are not vertical. Again, just my opinion but i have seen a lot of wing nuts at a lot of meets. ARA

Pictured below is my collection of original GM wing nuts as well as one chrome repro wing nut. The only difference between the 1963 and newer Corvette wing nuts and most 1963 and newer Chevrolet passenger car wing nuts is the chrome plating. Note the metal thickness of the chrome repro wing nut. It also appears that GM used different vendors over the years as the ears of the wing nuts vary in size and shape.

Chrome wing nut is GM # 219281
standard wing nut is GM # 9418699.

David, the one listed as NOS is what I would consider Typical factory production for C2. Other than the shape of the ears another telltale sine is looking at it head on as you have pictured and you can see the "Stop Sign" octagonal shape to it. I have I have restored many original cars and all unmolested c2's had that design (396 is the same just not plated) I have had hundreds of original GM wing nuts and if I were restoring a mid year for judging that's what I'd use. That wing nut is the top view of the same design Wayne M posted earlier.

The 67 Buick nut looks close I'd be interested to see more shots of that one. I have pulled many wing nuts off of Buick Olds cars from the mid 60's that were C2 style.

Rich, if i got to "cherry-pick" one from Dave's collection for my 67, it would be the one listed as "NOS" as well.

Rich,
Here are more photos. I bought the NOS 219281 chrome wing nut on 12/12/1983 from LIC for $3.50. The tag was labeled "63-67 AIR CLEANER WINGNUT (chrome, N.O.S.). GM # 219281 was discontinued Jan. 1973 and replaced with GM # 1385852. I assume that LIC bought the 219281 wing nuts from a GM dealership before they were discontinued but who really knows.

Were there any other comments regarding the other 3 items on that line? If not, a one point deduct for your wing nut is a classic example of a judge that does not understand how to apply the CDCIF judging matrix. One point isn't a killer, but it begs the question for the rationale of every other deduct on the mechanical sheets.

they also got me for the Paragon air cleaner lid with the incorrect silk screen.

Ara I know you sell a lot of "ginger bread" items for mid years and been around judging long enough. But with three suppliers of wing nuts for GM to maintain 25,000 wing nuts per day for all GM car lines. Do you really think every single one looked exactly the same every day for years at end. just look at all the other examples that are posted here. and who is to say that after 50 odd years that a wing nut has not been replaced. I know repro parts are muddling up the waters of whats original and not. but common sense has to come into play some where

That would merit a deduct on a separate line for Air Cleaner Assy.

Re: Identifying an original 1967 air cleaner wing nut

Keith, i do NOT think every wing nut would look the same. However, the Bowtie cars tell the story. As judges, we extrapolate data, knowledge and variations on every car - Bowtie or not. No car was made EXACTLY like the next one, but statistics, consistencies and patters emerge with a lot of the items on our beloved cars. Sloppiness of door weatherstip, sticker placement, etc. varied with which union worker was on shift that day. However, we've NEVER found a Chevelle carb on a 67 vette. Some things aren't going to happen. With the wing nuts, i would venture to say that the single most common one found on all (at least as my memory goes) Bowtie cars resemble identically the NOS one, the 72 Nova one and the unknown source ones. Believe it or not, there are variations in each of these as well -but the others IMO aren't similar at all. I take more pictures of Bowtie/Bowtie candidate cars than any frame off restored car because each one tells a story. In fact, the Bowtie cars help us restore the cars that need restoring - like the wonderful job you and your Dad did on your beautiful car. Each one teaches us things. If every Dunkin Donuts cup of coffee i had for the last 10 years i enjoyed, then it stands to reason that i am a Dunkin Donuts fan. ARA

Re: Identifying an original 1967 air cleaner wing nut

There is a nice photo of an original chrome wing nut (GM # 219281) on a 1,100 miles 1970 Z28 (Flint engine made 02/23/1970 with "CTC" code) in the link below. It looks like my original 1977 El Camino wing nut (photo above) except for the chrome. Click on "Photos", then "Requested Pictures". It is on the top row of photos, 2nd from the left, double click to enlarge the photo. This wing nut has "large ears". I'm sure that the 1970 Corvettes were issued the same wing nut since their engines were made in Flint. I assume that this 219281 wing nut was not made by the same vendor as my alleged NOS 219281 wing nut.

Re: Identifying an original 1967 air cleaner wing nut

It does not make much sense paying 150-165 for a wing nut that is probably a very minor deduction.

I must be really behind the times - is someone actually asking $150 for a single wing nut and is someone else actually buying it?

[Calvin M.]

Re: Identifying an original 1967 air cleaner wing nut

There are a couple on eBay now for $150 or more. Last year I saw one being bid up to $260+, and it hadn't met reserve.

All of this for a 1 point deduction...really????
