New US cast and machined 9.5" brake drums, where???
Not going to happen, new, unless one finds NOS or NORS drums made many years ago.
Through the 90's, into the 00's pulled select alum rear drums in the Pick -N-Pulls and crusher yards off 80's G body's, some 3rd Gen F body's, and even quite a few Cadillacs & Buricks. Only thick drums, if scored, didn't grab them.
On my own rear drum Pontiacs, that's what Ive had lightly turned, had cryoed, and have rebuilt backing plates with new wheel cylinders, stiffer return springs, and the special matrix brake shoes from Praise Dyno, now MusclecarBrakes.com. Also have numerous thick cast iron drums that have pulled off parts cars. Nothing wrong with running cast iron originals if they are thick, in my own cases, am trying to save rearend reciprocating weight.
