Rear disk brake conversion

[bugs4121]

Hey everyone............I know this has been brought up on different occasions but I have been saving up to do the rear brakes on my 72 K20 that has the eaton 3rd member dropout in it and now I am going back and forth on whether to stay with my drum setup or go with the disk conversion .....my drums are shot so I will have to replace those anyhow what I am asking is to have is all the pros and cons to both the drums and the disk and the best place to get the disk setup if I decide to go that route.
