I am building a highboy style 30 coupe on 32 rails I got from ASC and just last week got a set of 1960 Buick Electra 12 inch drums and the backing plates...plenty of articles out there and doing this conversion and the finned Buick drums look great
I run a BUILT DeSoto Hemi & 4spd with 4 wheel LINCOLN drums. Will Put you in the Dash if you jump on the brakes. Drum Brakes are the ONLY way on an Open wheel Hot Rod, Leave the Disc's for the Street Rod Crowd.
