Why are the 11.75 Brake Better?

I checked the set I have and they are the pin type. Is that what you were looking for? They made pads for sliding calipers also. I really hate the "we'll throw a generic picture in and add a disclaimer" nonsense. Why bother, just pull the part and take a picture of the part you want to sell.

The Dr. Diff kit comes with slider-type calipers, that's also the type on my car currently. It's weird Hawk sells the pin-type ones it since it seems that type is less common on the popular A/B/E-body Mopar muscle cars.
