11.75" caliper brakets needed

How come you want sliders and not the pin type? Seems on Summit and other part stores the better pads come in pin type only. I got a pin pair to replace my sliders from a 76 Cordoba. These are for the big front rotors, like the R bodies cars had--right?

When ever I get to doing my brakes I will have a slider set for sale. Heck I take $50 plus shipping for them...but I'm too broke to buy new rotors and calipers and pads right now and brakes are doing ok...but I know my rotors need changing.
