Another 8 3/4 question

I found one site that used 51.4" flange to flange . 52 5/8 was the most common # though.
I just dropped my axles off at the driveline shop today and would prefer to have the housing cut only once...lol....

Now I understand the whole big brakes vs A-body brakes . it's the width of the shoe that is the difference . right ....? That never occurred to me before .

51.4" is wrong. That website needs to take it down because it's caused so much confusion over the yrs. 52-5/8" is the correct stock width.

I'll be running Moser's so I guess I'll be looking for some 10x2's or 11x3's . Will I have to worry about the proportioning at all ?

Like Tom, I haven't had a problem using the stock valve either. The stock valve is not really a proportioning valve. A proportioning valve limits how much fluid is sent to the rear brakes. The stock valve on our A-bodies is just a safety valve. It only senses when a brake line blows (either front or rear) and the valve inside moves to close off the blown side and apply the fluid to the good side. Some factory A-body valves also have a residual pressure valve that gives the brakes a firmer pedal.

I have a set of backing plates I took off a B-body a while back. PM me if you are interested. Their bare backing plates but they do have the parking brake hardware so all you need is to rebuild the brakes, which you should do on any set of brakes you put on your car.
