Hydroboost is suppose to be better than vacume.
I swapped in a 1Ton Vac Booster/Master combo from a 72 K30 pickup.
AJ wrote up a great post about this type of swap..it's here somewere if you search for it.
Lots of fab shops make the disk brake swap brakets like DIY4x, the calipers are usually from a D44 or 10bolt front. If you want an E-brake I've read some guys use Cadilac rear calipers as they have an e-brake lever on them. I just leave my rig in gear and carry a 8" long 4x4 chunk of wood. Well that and I have a line lock on my front calipers if I need to for short periods of time.
