10” backing plates 8.75

More info needed. It's imperative you match the backing plates to the shoe width. There are different offsets depending on the width. A BP for 1.75 shoes is different than one for 2.5 shoes.

thanks for the reply. So my plan is to discard the a-body sbp axels, get a set of after market bbp axels, stock length. Then build up my 8.75 with 3:55’s in my 489 case. So I was told I need the bbp 10” 8.75 backing plates.
