There was a thread on the old forum, will start a new one here.
Standard Ford Mustang, San Jose items for a '67 Shelby with 10-spokes or Hub caps/Wheel Covers.
The Wrench has a 13/16" end on the wrench - cast bell end with stamped steel handle with end to pry off wheel cover on the other end. The top item in the composite image below.
The '67 Shelby's with the Kelsey Hayes Mag Star's used different lug nut that are 3/4". This caused some issue as some cars did not get the correct sized wrench and there was a memo written regarding this. There is a 3/4" wrench that looks the same but has a smaller cavity on the bell end, these are not easily found and many have bought or been sold the wrong wrench. The handle end is the as the other and I believe judges prefer that it not have any holes in it, although there may have been some difference of thought on that others will know better. (The version with holes was for Corvettes as I understood it.)
The three different wheels (Mag Star, 10-Spoke aluminum and steel) each used a different lug nut, see image below.
The standard Ford Mustang jack has a 13/16 nut on scissor jack, the Mag Star version has a 3/4" nut. Marcus Anghel and Bruce Klier did a great multi-page PDF summary on Ford jacks and hopefully he or someone else can re-attach it to this thread. There were some differences of opinion on the San Jose Jacks and I'll let others expound on that.
The Jacking Instructions typically went on the underside of the trunk lid on a Mustang BUT since the Shelby's were shipped without a trunk lid to Los Angeles the sticker was in one of two places; on the back of the trap door or on the raised section under the spare, see attached images.
