Brakes from 73-87 pickups.

[edwardgonzalez]

So work has finally begun on the 71 pickup I purchased last year for $500. I needs a lot of work it has been sitting for a long time. It looks like the brake system is my next step. It currently is disc in the front and drum in the rear. I pulled the top off of the master cylinder and it was dry and full of rust. I'm thinking I may have to change everything. I want to save some money and upgrade to power brakes also. what is my best route? Can I pull the booster, master cylinder, and proportion valve off of a 73-87 pickup? they seem to be the most readily available. will I still keep the hoses from the 71 system? how hard of a swap is this? what should I know before tackling this conversion? I know I'm asking a lot of questions but I want to know as much as I can about this before starting. Any help will be greatly appreciated, thank you.
