Air Cleaner Wing Nut

[Paul O.]

Need opinions on some wing nuts I have come across and had them plated. I feel they are correct in size, thickness and overall configuration. Here are a few photos now I need opinions. Thank you to all in advance.

Take some pictures with a dime resting in the center of the wings so we can get a feel for the diameter. I thought I had a picture of mine, but I can't find that one. The dime fills the opening between the wings.

Ron that would be a #219281.

Paul,

Put the dime in the groove so it's standing on end.

Re: Air Cleaner Wing Nut

The 219281 goes back a few years and the wings of the part you show would not be consistent with those parts that are generally selling as originals for very high $$$. Didn't I start a thread about this a few weeks ago?

the thread i remember reading took place 9/28/11. discussion was on 55-57 wing nuts. gary chesnut measured his wing nut at 1.25" wing span, .375" wing height and .703" base diameter. i did not see any dimensions given by anyone with a mid sixty car.

What I do not understand is you ask a question an answer is posted you make a statement without giving a complete answer of what the inconsistency you see and why. I pose a question of where the other thread is so I could read it John has to give me an answer to that. When I read that thread you have a photo of 4 wing nuts ask which is the real one. But you never give an answer to your own question you posted.

I realize the 219281 wing nut was made for a very long time but the wing nuts configuration also changed over time. What was installed on a 56 corvette I think from the photos posted in the other tread do not look like the ones that were installed on a 1970. So if you could what are the inconsistency you see in the wing nut photos I posted?

Re: Air Cleaner Wing Nut

The L1963 to 1970's Chev. passenger cars used wing nut # 9418699 starting sometime in the middle of the 1963 production as per the assembly manuals.
GM # 148312 was replaced by GM # 9418699 on 2/12/32 (63 Chev. AIM).
I have nine 9418699 wing nuts from Chevrolets in the 1960's and 1970's and the measurements seems to the same as the chrome 219281 wing nut. Pictured below is a wing nut from a 1963 Chevrolet on the top and a wing nut from my 1977 El Camino (orig. owner), GM # 9418699, on the bottom. I believe the top wing nut is GM # 148312. Each wing on the top wing nut measures about 0.29" wide while each wing on the bottom wing nut (GM # 9418699) measures about 0.37".

Why would anyone buy a reproduction chrome wing nut when all you have to do is find a nice L1963-1970's passenger car wing nut and have it chromed.

Thank you for your input do you know when the 9418699 was introduced?

Re: Air Cleaner Wing Nut

David,

My 1963 AIM calls out the #117204 for the air cleaner wing nut. Is this chromed and stamped like in your pics or a different style?

If it's different is the 63 AIM using a page from the passenger car model.
