8.75 backing plates

I dont know if they are the same,my thinking is the 2.5 b body ones would not put the shoes where they need to be on my drums.I will do more resurch and I dont need clean,The nastier ugly greasey pair is better cause I get gratifacation getting them nice.One look at my hands and you would understand.Will get back to you when I figure out if they will work.THANK YOU.Mark
