Slider type Disc Brakes

I have to say that the search function does not work well here. I have slider disc brakes on my K frame. I would like to know what I need to do to change it to the pin type calipers?

This post seems to have some information on it by just by a quick scan.

This is the search that I used so it might bring up more information too.
