Rear Brake Backing Plates for 8 3/4 Diff

OK, thanks for the quick reply! I should take a lesson from you! LOL! What I have is an A body 8.75 housing. Those plates should bolt right on! What I will do is measure the center-to-center length of the holes in the flange where the plates bolt on. I'll get that measurement to you later this PM, then you can get a measurement on yours. I expect them to be the same. I'll get back to you!
