Does anyone know if the stampings on the back of the pad mean anything? My car came with a bunch of spares in excellent condition, but they've been run for a least a little such that the original color coding isn't obvious. So, I'm trying to figure out what's what? I know that one of the numbers (635 & 636) refer to 1.8L pads.
(I've contacted GLoc but they haven't been responsive so far).
