No, but nice picture.
I figured it out myself. My installation is done. Thank you though.
I went with matching grey to the EPB.
What I was looking for was the center line to center line on the EPB adapter. I was having issues with the thickness of the adapter and where it located the brake pads in relationship to the edge of the original Pantera rotor.
I can only speculate why in some issues but it may be that what is being offered as an adapter was done using the 65 Mustang rotor and not the original Pantera rotor.
The Mustang rotor varies from the Pantera rotor in both thickness and outside diameter. The Pantera rotor is thinner and larger in diameter. That effects how the adapter is dimensioned as well.
No problem now though. I found that I needed a 1-1/2" center to center and a 3/8" thick adapter.
As far as relocating the Pantera rear caliper to the front, for my car, it isn't a simple bolt on.
The thickness of the mounting tabs in the front vary from the rear.
On the right upright, the tabs were machined 1/8" thinner and on the left, 1/16" thinner.
My reaction to that was because the left and right varied on the front tabs, I thought that those were "mis-machined" initially from the supplier and because they didn't want to throw them away, the mis-machined tabs were just located where they were never intended to be used by the factory to begin with.
I didn't like the proximity of the "outboard" mounting brackets for the original mechanical handbrakes when the calipers were mounted in the forward position.
I wanted to see what everyone else had done with that. There are amazingly little photos of that detail, as well as no mentioning of the tab thickness variation OR the variation of the adapter using different rotors, so that's where my installation needed to be re-engineered.
My solution was spacer/shims, to center the Pantera calipers correctly varying from left side to right side, and removing the "outboards" entirely.
That's why I asked for a photo but even Pantera-Electronics couldn't supply those.
Hey. It was a fun project and the kind of thing I like to do anyway, so no complaints from me.
There are LOTS of places on this car where sometimes even the slightest variation from stock involves considerable fabrication AND "you should be careful so you shouldn't get killed".
