72 blazer master/booster upgrade help

[72blazer_mud_bogger]

i have a 72 blazer and i was told that for this upgrade i could use a mid 80's 3/4 ton booster and master cyl kit. how much of this will be close to bolt on and how much will i have to fab something together. i am looking to in the future go to 14 bolt rear and dana 60 front. also i already have problems with the one in my blazer now, as well as i will be putting some lift and bigger tires on when warm weather comes back. any help on this would be great
