Oops, sounds like I stand corrected. I bought some of the calipers from a local parts house and tried to bolt them up. It was a no go. Maybe they gave me the wrong ones. Maybe I should try that again.

Tristan, is it as simple as chnaging the caliper AND the caliper mounting bracket which bolts to the spindle

I hope this works, if so, and if I can locate a pair of the brackets, I
may have bigger brakes for Sebring short course...
