Rear disc Brakes on 8 3/4

hm, a nice new pair of brackets.. :)

well, I have another Point while we are here. The bracket A which is the one bolted on the axle. It is Plasma cutted and I assume you drilled the holes first and cutted later? I am asking because the bracket is a little bent I saw as i was drilling new holes. Guess the heat from the Plasma cutter made that.
And I also had to open a bit the holes for the screws to Mount the other bracket for the caliper.
