Disc brake conversions 1972 k10

[MDFarms]

Could I get your ideas and thoughts on rear brake conversions? Worth it or not? Went to get rear drums for my 1972 and some drums are available and some are not according to size. Thought about disc brake conversion in past but not much since. Wahst the options for E-Brake when converting? I know its still available but not sure whats involved?

On front calipers is it possible to get GM rebuilds? Or stamped GM housings?

Who make the best overall conversion? I see Captain D's on 2 wheel drives not sure if he has 4x4's?

I know distrubution valve needs to be changed and maybe different booster?

Any threads with conversion pictures on 4x4's

As always you help is greatly appreciated!
