8.8 swap

My 67 is staying 8.75 with KH 10" x 2.5" finned rear drums. I built that one up and emptied my wallet to do it before i knew about the xploder 8.8 swap. I bought this one for my sons 69 notch. I figure this rear with discs and a front disc setup using M body spindles, and 11.8" cordoba rotors, 2.75 calipers and caliper brackets will probably stop on a dime.
