Sliding Caliper Brackets for 11.75 Rotors Upgrade

I need a pair of caliper brackets for the sliding type single piston calipers for use on 74 A body spindles. Currently I have 10.98 discs, I want to upgrade to the 11.75 x 1 inch discs so I need the caliper brackets off of a B Body (78 Cordoba). PM me with what you've got. Thanks
