Need answers; hydroboost swap and Eaton disc conv.

[dewdew]

Two questions. I am looking into converting to a hydroboost setup and am trying to find out what vehicle I can steal all of the parts from. I have spent many hours reading old posts, but could not find real specific answers on all parts needed. I would need to replace hydroboost, master cylinder, steering gearbox, and power steering pump, right? I will need a disc/disc master and would like a newer style (aluminum body, plastic reservoir) and possibly a gearbox with a tighter ratio. Is there one vehicle I can use parts from, or could you tell me which vehicles? This would all be going on my '71 C20 Cheyenne. Also, my truck has an Eaton rear axle and I would like to do a rear disc swap. I have read that the 14 bolt brackets will work with the Eaton. Is this correct? Is there any differences at all? Thanks for all your help in advance.
