Tri-Y Header Bolts -
« on: July 24, 2014, 03:54:19 PM »
What is the style, length and head markings of the bolts used on 65 and 66 Shelby Tri-Y headers? Was there a washer used? This is for an upcoming project.

Header bolt style appears to depend on when the car was but - 65-66 isn't close enough to provide a solid response

Unlike after market headers no washers were used

I was trying to open a general dialogue but specifically, Feb and Mar 66 builds, a second car owner asked me about an hour ago.

By narrowing it down it limits the number of files I have to look through ;) 

There were a number of different suppliers used during 66 , an unnamed company and ROCKFORD with a different head designx  as shown below




Doubt you will be challenged either way if the car is shown (believe some judges will like to see the Rockfords though)  - Did find the use of both on  original cars during 66 up through 2268 where I stopped (its later than your focus area)

The Rockford ones i believe were carried by Virgina Mustang - don't know if other places carry them, The other version I don't believe is available except from a donor car

Looks like they are 3/8-16 bolts approx 3/4" long will remeasure to make sure

The countersunk type was used on 65 Shelbys and I believe they are
available from AMK.

These are the only ones that are available now that I am aware of.  Unfortunately, we are no longer able to get the "Rockford" marked ones.

 Hopefully not too far off topic but my question is more of who makes a "closest" match to the original Tri-y's that Shelby used?? Many brands out there now just looking for a close match for my daily driver clone... I try and keep it as close to "real" as possible.  ;D

Believe Shelby Parts & Restoration in Green Bay makes the closest reproductions currently. They come painted or jet coated. He does them in batches - not sure what Jim has in stock at the moment
