" I wonder if the larger Jeep rotor could be adpated to the AMC spindle?
" The 82-3 Concord Caliper bracket would be fairly easy to copy in a
" format that moved the caliper to where it needed. I'll have to see
" which axle is under the front of the 88.

" Ok Andrew, I've got a 1982 Concord setup for my 1970 AMX, is there a caliper
" bracket that will let me use the 1 inch larger rotors you referred to??
" Please more info!!! I just got a set of 18x9 inch wheels and need the
" largest rotor possible to prevent the brakes from looking so teeny tiny.

" As in 1" larger diameter -- 12" rotors (IIRC the standard Concord rotor
" is ~11")?? If so, are they the same thicknes (0.8x") and do they use
" the same bearings? If that bigger rotor will fit a Concord spindle, and
" is the same thickness, just a new cut from 3/8" sheet steel caliper
" adapter will get you a bigger brake -- will just require 15" wheels.
" Should be the same thickness if the same caliper is used -- Eagle used
" same thickness rotor as Concord IIRC. 


so -- i looked into my napa brake book again, and --
concord rotors are 10 3/4"
1pc ['86-'93] xj rotors are 11 1/16" - not alas 1" larger.

they do use the same #6/#2 bearings.  they're about the same hat
depth.  with the same calipers and pads, they must be the same
thickness +/-.  but they aren't much bigger.

btw all 'new jeep' [xj onward] rotors appear to be about 11 1/16".
