No it's not that hard. I had a 72 with front disc but no power. I picked up a booster from a mid 70's C10 and used it. Drilled a couple of holes and had to do a little work to the rod that hooks to the pedal to get everything to adjust out and work correctly but not that big of a deal. Last week I installed a booster and MC from an Astro van in my 66 C10. Again drilled a couple of holes and a little bit of work to the rod and she was hooked up and ready to go.

Depends on your abiilities to know how to adapt and make things work properly. Early trucks 72 and older use canitilever set-ups on the under hood side, later models use a single rod from pedal to booster, that's why the mods are sometimes needed. If you've got the proper brackets off the correct year truck, it would bolt right on. USing the later model stuff bolts the booster directly to the firewall and makes for a much cleaner look.
