I converted mine to disc by making my own kit. I used rotors from a 78/80 Chevy K10 which are 6 lug. I used calipers from a 78/80 Chevy C10. I made brackets from plywood to get the proper dimensions, then cut them out of 3/8 plate steel. I used the original hubs. I installed longer 2 1/2 inch studs because I need a 1/2 inch spacer for the wheel to clear the caliper.
I did the tapered bearing swap. I had the hub surface trued to mate with the rotor. I used a 1/8 spacer behind the hub to allow for the offset required to get the rotor centered.
