So the question is now, is there a good source to get a proper designed hex head bolt if the choice is made to go in that direction. As I have considered this I have not been successful in finding original hex bolts or something close. Anyone know of something?

Nice discussion. I love you guys. I wish I had seen this earlier and saved all the hostile statements back and forth and offened egos These are the facts. FACTS. The bolts used originally by the AC factory, where the comp style filler was absolutely installed, were BSF hex bolts, period. My brother was at A.C. in 1967 at the parts counter at A.C. following my orders to get three complete Comp fillers, necks and all attaching hardware, for the car that I eventually going to own. I have them today 2013. Shelby, when the cars were painted, changed the bolts to aircraft surplus American fine thread low height indented thinned head bolts. He did not machine anything thinner. They came that way and he selected them that way. The bolts he used have a spherical circular depression in the thinned head with a thin AN washer added to protect the underlying aluminum flang. No stainless steel, machined, phillips anything. Period. There is a call out number on the head that indentifies the manufacturer, type of O.D. fit and basic thread size. No length call out on the head data. I'll give you all a hint, the company was in walking distance of the Shelby factory. Imagine that. Hope this helps.

Smoothed and chromed, looks like with the lack of radiused corners someone turned them down then puffed them.

NAS thin head style. Military surplus was cheap, high quality readily available stuff.

The bolts on the red car above are Premier Supertanium grade 10. At one time the benchmark chassis fastener in Nascar racing, but a bit of overkill for the application here.

All the cars I have seen are hex in the early 3000 series.
Sal did a great rendition however the accuracy of 47 and 50 are hard to dispute. 3047: Jack bought the car with a fresh coat of solid blue. The car had FIA gold wheels and had nothing missing from the Carter Getty days. The stripes were added by jack and Paula one Saturday afternoon with shaker can white and masking tape. From what he had told me the car was very complete and untouched. Wanna see picture in blue pre-stripes????? :) 3050: Also another untouched with painted bolts.. Never felt the machined bolts were correct as that was extra $, anyone in MFG knows time = $$$. Didn't make the car faster. My vote = bolts Here is 47: |
Where can you get them?

Until I was lucky enough to find a stash of really cool looking Supertanium bolts, I was using the titanium aircraft bolts with the thin head. I have several 1/4" bolts that I am no longer and would be willing to sell for a very reasonable price if someone wants them - I have a couple of different lengths. They look very old school because of the color. Here is a link to some for sale on ebay - by changing the suffix on the P/N, you can get different lengths:

I was going to use those on my car also but I found these Supertanium's and I will be using those instead... Attachment 22932 |
Actually as previously stated SAI would by military surplus hardware for, cheaper to get and higher quality than the hardware store would offer. SAI tended to use "CXS" stamped hex bolts (mostly cadmiumum plated) when building out competition Cobras, areas of use included everything from Weber linkages to suspension hardware.

Aircraft Spruce and Specialty Co. for AN or NAS style bolts...

I just whizzed out a few of these if they help anyone trying to index or raise them for clearance.
