10"x 1 3/4" brakes on 8 3/4 rear end

Yup, thanks. I just ordered 4 nice new ones for my project. The ones that I have are slightly different, they have like a wasp neck right where the rubber cap would be on the wheel cylinder, possibly like a grip on the pin. I'm sure that these ones from Rockauto are generic in design, so that they will fit a large variety of applications though. We shall see in a few days, thanks again.
