Once more we all learn from Dan. Thanks! More info to file in my mental hard drive which is full so I have to delete something to make room. Usually something my wife asked me to do...………..

You are welcome. These things are very complicated 'factory original' wise because tapers and inner diameters were machined differently for different wheels, different chassis number ranges, so on and so forth.

Example: Most race Cobras (roadsters and coupes) SA completed with forged aluminum nuts had four different nuts engineering wise per car. There was the left hand and right hand threads of course but also nuts intended for wheels machined for front hubs on front hubs and nuts intended for wheels machined for rear hubs on rear hubs. Post factory days users got in trouble mixing where wheels went and which nut went where. In the 1970s I saw on ex-racer with rear nuts barely on one and a half thread turns.

I have at least one of every version nut that AC, Shelby, FAV, or Kar Kraft/HM used on street or race Cobras, all the GT40 variants including J-cars, and 427 Cobras except the three forged steel production variants. Some I know which car they were originally installed on.

I don't have samples of the forged steel ones because I get too soft hearted when somebody doing an high end restoration 'needs just one more' nut to complete their car. I have had several of all of the forges steel ones in my hands but all went to high end restorations. (Not interested in the 1968 and later ones sold as replacement parts; either version of forging tool.)

Someday I want to create a wall display in chronological order but I have to come up with some forged steel samples...................
