Not sure why you suspect front-wheel drive would matter.
Here is how I determined my brake pedal will be in about the same place w/ the MC for a 95-99 Breeze w/ ABS ($25) on adapter plate ($28), using the manual brake rod for my 64 Valiant. The thickness of the adapter plate doesn't make a tremendous difference in where the pedal will sit. You should always remove and re-position the brake lamp switch. People must be foolish if they think the the switch won't need moving. Some seem to think it should act as a "pedal stop" (I think false). The factory put adjustment slots in it.
I put a new rubber bushing on the end of my manual rod. Seems it will lock it in fine in the new MC piston. Indeed, I wasted one in a test fit when I had to remove it to install the boot and the rod wouldn't come out without destroying the bushing.
BTW, I mounted an adjustable proportioning valve on the bracket I took from an Intrepid. That will allow me to easily use front disks later.
