I have a 1994 Chevrolet S-10 4x4 4.3L with VIN code "W", and, while replacing the front brakes, I discovered that the threads on the caliper mounting bracket are stripped out or the hole is worn into the shape of an egg (a very disturbing revelation, I assure you). I've spent the last several hours trying to find a website or dealer that will sell the part. The biggest obstacle I've run into is that every site I have checked is either giving me caliper rebuild/repair kits, the caliper housing itself, or simply brake pads. I don't need any of those things: I need what the caliper bolts screw into to secure it to the axle assembly. Help!
