67 Magstar Question

[capecodmustang.com]

I have numerous 67s with Magstars however I've noticed some of the jacks are 13/16 rather than 3/4 for a Magstar bolt.

Is changing that bolt to a 3/4 the only difference?

Is the 3/4 bolt the only unique piece to that jack?

Thank you!

A 3/4 lug wrench isn't going to be much good trying to use a 13/16 drive jack.
 Most very early mag star cars did not have a mismatch from the factory but some did. The factory or dealer was instructed to tell the owner to buy a auto parts store additional lug wrench for the jack and they would be compensated.This mismatch situation was quickly corrected. Later cars ether had the correct matching lug wrench and jack or they were were changed out by later owners. The drive of the jack would be 3/4 and so would the lug wrench. The rest of the jack was the typical SJ style jack.3/4 drive jacks are much harder to come by then 3/4 lug wrench . Unlike a lug wrench you can take the drive screw of a 13/16 jack and machine it to a 3/4 size.

So you're saying by changing or modifying that 13/16 bolt the rest of the jack is the same....?

Yes , I said that the rest of the jack is a typical San Jose jack.

Of course you take the drive screw completely out of the jack to modify it.

I thought I should clarify and make sure you are aware that there is a typical SJ style jack and a typical Dearborn / Metuchen style jack. Two different styles of jack . Make sure you use a SJ style.

Thank you JD...
And Bob too...

Never realized so many jacks and lug wrenches lost their way over 50+ years

Here is a picture showing the differences at the drive nut end of a typical jack used in Mustangs built at the SJ plant the other is the typical used in Mustangs built in Dearborn or Metuchen.

Bob...
Might you have a photo of the part that actually lifts up...?

Or is it the same as the Dearborn Jack?

Thanks JD. The items circled in the picture are the most important part of the determination.

Never seen this but if someone used mismatched jack on early car or displayed with a period correct auto parts 4 way it would be considered concours correct

Say What? If your going off of Bobs comment then IMO no since it was a suggestion for the buyer to purchase one but not supplied with or with the car when sold it appears.  Hadn't heard the story before but on the surface this appears to be a Day 2 addition if I heard that before. Maybe your response is missing the "?" at the end

I hope it wasn't meant to be but your question comes across as a little snarky.The written word can be tricky. Factory memo document the circumstance. Typically like with anything else out of the ordinary (I believe this qualifies)reasonable proof for a specific car would be expected. Reasonable proof is still a expectation with MCA venues. I assume things haven't changed in that regard with SAAC.
