Where do I find spindle hardware for my 14BFF. I am in need of the spindle flat washer, spindle nut (also called the inner spindle collar), spindle lock washer, and the spindle lock nut (also called the outer spindle collar). I have been all over Bill Vista's 14B bible, GM parts direct, etc. with no luck. Are these parts only availiable from GM? How about Randy's Ring and Pinion or West Coast Diff? Anybody have these numbers or know how the heck I can get them?
