I know late to this, but, I had to chime in on SSBC

Caveat emptor
Caveat emptor is Latin for "Let the buyer beware".
2.5 stars. '66 C-Body Drums asked for full disc conversion. First inspection, front caliper assembly bolt missing head (sheared prior to the powder coated finish I had ordered extra). Another caliper had been scratched/dragged before they shipped it, exposing the metal. I might have epoxied it and said nothing, but, it was on the exposed side. Sent pics and they agreed (duh) these was their issues. Instead of sending two replacements, they said they had to use my scratched one to redo, delaying a month the whole process. Parts hooked up first time and worked - sort of. Caveat Emptor? My '66 Midland Ross booster worked great on my big and heavy drums (when not fading). The sales guy (I ordered directly.) never mentioned/suggested using mo'powa (Scotty) to push that new 'Stang dual master (came in their kit) to clamp those discs. I get one good shot at stopping, but, that's it. Calling Wayne Brown (TheRamManINC.com), Monday. My compliments and thumbs up to the experienced forum members that have cautioned the readers on underpowering your braking systems. Caveat emptor.
