One thing to consider as it would be best not to fit pads until you have the bracket you intend to use "for best", as variation in the machining is possible on the 2nd/3rd World repros. It's generally agreed that machining the front pad "seat" is essential; the body sides are not a controlled surface, if that is the correct term. I should add perhaps that since the rear pad mating surfaces were reportedly machined after the pad was fitted to the body, it might be wise to carefully run the end mill over that area as well before fitting a reproduction pad on which those surfaces are already machined.
