replacing wing nut bolts that hold air cleaner plate

[Copescobra]

I recently lost my original wing style bolts to the top of the air cleaner plate.
thought I put them in my pocket but obviously screwed that up....

My mechanic commented that they are slightly larger than most you will find at Home Depot
or places like that.
Any idea who or where to go to find a replacement set?

AMK sells them.  Part number F-375.

I have such a hard time posting pictures here it was easier to post on the concours forum and provide a link to the post and picture here. Others there hopefully will benefit too.    https://www.concoursmustang.com/forum/index.php?topic=26306.new#new

Neither of my air cleaner tops have notches for the wing nuts. What are they supposed to look like?

Don't panic the diecast oval lids were typically plain. The genuine early sand cast lids typically had the indentations . The hipo lids and a large portion of other sheet metal lids had the indentations to lock in the wing nut. Sorry I am not going to fight the picture posting gauntlet tonight. I sure wish someone would put a quarter in the meter and get it going.

There was a Ford Pinto flat washer that I came across that has a thin rubber on one side, and has quarter notches in it. It is chromed and works well with the wing nut which to me looks like a generic Ford air cleaner wing nut.

The wing nut is easy to come up with the washer is tough.


Someone needs to wake up the moderator here to fix the picture scenario. It sounds like it's above his pay scale or just doesn't care?

There have been cracks showing here all over the place for some time. At some point this is all going to crash completely for good.

My Cobra 2x4 top has 2 indentations going front to back for each wing nut but my NOS Shelby Autosport SFMK-9600-C 2x4 top doesn't.

My two original pressure molded tops do not. I'm wondering exactly how many variations there are of these components, including the bases?

I'm not sure anyone can say scientifically how many there are, just speak in generalities and maybe we shouldn't even use the term "original" since there really isn't documentation that would hold up to a jury in a court?

I'm thinking they are similar to the 10 spokes in that sense?

"Pinto"washer was used on many Ford engine applications, but I think that started in the 70's                                                                                                                                                                     
  air cleaner nuts = 1 with dimples and 1 without ( where did I get this one ) Sorry I took picks but uploader is full ??

The one without dimples will work but is not historically correct .The one with one dimple is the most common ,the wing nut with two dimples was least common but also used.I have only seen that on on 65-67 applications but that doesn't mean it was not used later. The wingnut style being discussed with no dimple is a knock off IMO. AMK Products sells the correct looking one as mentioned before.

I have 4 different original bases. One with a 90deg fitting, one with a curved tube to the right, one with a curved tube to the left and one completely different with ribs on the bottom side and a rubber plug where a tube could go. Part number S7MS 9600 B  Does anyone know what that one is for?

Gaines is your best bet. Is the spider one cast or pressure molded/cast?

I don't use the term original or reproduction. I just describe them and let the interested onlooker determine that. I can't prove it either way.

There are just too many variations I've come across and no one has seen all of the 67 GT500's when then were going out the door at SA plus a really good reproduction could fool anyone anyway.

It sounds like you are describing two different styles of Shelby bases. Sand cast vs die cast.I can say that the only duel four base with the S7MS and ribs is diecast . It could be ether a over the counter version without the fitting or one that someone has modified. I have not seen evidence that the base was serviced separately.  The assemblyline base would have had a elbow fitting . The 90 degree version was only used on the sand cast version. The original is a steel fitting and not a cast aluminum. The correct steel fitting is swedged in and although difficult will swivel with enough force . If it is cast in then it is not a original Shelby base.  The later style version of the sand cast base  has the curved steel fitting. The fitting is swedged in place. You should be able to swivel the right and left facing curved elbow with enough persuasion . These are some general details but there are more nuanced ones.  The only way I could say for sure is to see pictures of the bases.
