Ok on 67s, but redesigned brake calipers dont work with 10 spokes.
Well, that's mostly true. The real culprit with the 68-69 brake calipers is the casting flash on the caliper and the thickness of the brand new production brake pads.
Since fitting the early '67 type (to a '68) without the cast in spacer required polishing down the outside of the caliper itself for clearance, that was a no-go as far as Ford was concerned.
The clearances are so tight that it likely would have varied from car to car and no one wanted to get involved in that.
IN ADDITION, when you go to the '68 type with the cast in spacer, it makes the tire to fender clearances even more of a problem, particularly on the GT500's which sit just a tick lower in the front then the 350's do.
When I had the copies of the original invoices, there were 5 cars invoiced with them. Two went to Japan and three to Spain. No domestic cars.
No one ever explained exactly what the combination of what was done to those cars was OR who did it. Likely it was given to an outside vendor because for sure it wouldn't have been done at Metuchen. I doubt they ever even knew what that wheel looked like.
IF they were done by Smith, then that would mean someone had to dismount the production Goodyears and remount them on the 10 spokes.
Having personally done this with both types of wheels on a 68 GT350, I'd speculate that it was Smith that sent someone out in the holding yard with a disc grinder and had them fit the calipers to the wheels. That's the simplest thing to do to avoid having to roll the front fenders and possibly bend up the wheel well trim as well.
I'd say that after doing those 5 cars Smith just would have said, "screw this, not available". Of course that was with 1,900 invoices missing so unless Marti did a curteousy print out of all '68 Shelbys just for SAAC, then it is possible there were more then 5 cars invoiced with them?
Ask Vincent. He was trying to make a deal with Kevin for a complete '68 print out. He was looking for W cars too.
Marti eventually conceded no W's for "68 Mustangs. That has Vinman's fingerprints all over it.
