does anyone know where I can find a front brake CALIPER MOUNTING BRACKET/BACKING PLATE or whatever it's called for an 86 k-5 blazer 4x4 I have checked dealer, napa, all the usual supects including salvage yards in the area. no luck at all. the blazer pulls hard to the left when you hit the brakes. i replaced calipers/rotors but there is a caliper bolt that won't tighten up so i think the brackets threads are stripped causing the caliper not to engage all the way. any help on this subject would be greatly appreciated.
