Any '65 and newer Dana 60 or 8 3/4" rearend with a 5 x 4 1/2" bolt pattern can use the same 10 x 2 1/2" backing plates. But, will the 10 x 2 1/2" backing plates from a 8 1/4 with a 5 x 4 1/2 bolt pattern fit the Dana and 8 3/4 also?
Have front disc now and just completely rebuilt the rear brakes last summer. I am looking to buy a Strange 60 soon and reusing my rear brakes would save me a pretty good chunk of cash.
Related: My 78 Dodge D100 had the 8-1/4 rear with 11" brakes. When the rear end died, I replaced it with an 8-3/4 from an earlier model pickup. I swapped the 11" backing plates over to the 8-3/4. The flange pattern bolted up fine. Hope this helps.
Let me get this correct. You can interchange the backing plates 11" and 10" between the Dana 60, 8 3/4", 9 1/4", and 8 1/4".
Thanks for the reply. I will add that the 8 1/4 will work on a 9 1/4, as I just swapped mine last night.
If ever need bolt circle dimensions go to wilwood web site , they have all the backing plate dimensions for almost any rear axle
