70 blazer axle swap D60 & 14bolts need help with brakes, thanks.

[jeffy]

Howdy, I'm needing ideas/information on a braking setup. I plan to change out my 1/2 ton gear for 1 ton stuff. Thanks for any help in advance, its appreciated. Here's the question(s):

What are others doing to support the larger braking systems when they convert?

This is my situation. I got a good deal on a complete running 1984 1 ton chevy truck (D60 disc, 14bolt drum). I'm planning the axle converstion. I'm unsure about how to proceed with the brake system. The donor truck has hydralic assist or 'hydro boost' brake setup. It looks stout and has been factory 'engineered' to work with the 1 ton brake parts in the wheels. I think I'd like to use this hydro gear but not sure exactly what I'd be getting into - Not sure how difficult or complicated the conversiton would be. The blazer (70) has a power boost drum system so it seems unlikely mounting holes for it and the pedal assemblies would mate up with minor reworking, etc.

On top of this, I'm also looking at swapping out the auto for the 4 speed tranny. This work would require (I think) that the pedal assembly out of the 84 truck (hydralic clutch (?) be reworked somehow into the 70 balzer. Is this a seperate stand alone project or does it relate or facilitate the possiblity of re-using the hydro brakes in the older blazer?

The blazer's motor is a 350 the tranny a TH350/NP205. The donor's a 6.2 liter, it has 4 speed SM465/NP205.

Again, thanks for any info you can supply.
