273 clutch help

Hi all, I ordered a 10' clutch from NAPA for my 318, 273 flywheel. Then, I found out about Brewers cp-10 kit, which is what came out of car. Previous owner put the disk in backwards!
My question is, is Napa's 10 inch Borg-Beck clutch the same as Brewers cp-10? Car is a 66 Dart, mild 318,273 bell housing and flywheel.Want to put the "strongest" clutch in that I can w/out going to a 10.5 inch. Any help on this would be more than appreciated!
