They were in great condition other than being stuck and full of crud. I honed them, cleaned all the little ports and painted them. I got the new 7/8th kits from my local FLAPS yesterday. As I was putting them together, the little piece of paper in the box said they are a new style kit like these and not to use the aluminum piston cups. Sounds good but...if I don't use the piston cups, what do the brake shoe pins fit into??? I have to use the cups don't I????

I'm not sure what the heck they are saying on that piece of paper. I thought I was being really stupid not understanding how this would work. Thanks for being with me on this.
