HydroBoost to Vacuum Assist?

[C30Seenemall]

Anyone know if it is feasible to convert my 75 Chevy C30 lousy hydro-boost setup to a vacuum assist setup?

The hydro-boost is giving me nothing but trouble!
It has always made the most horrible gurgling, squishy sounds and braking while turning has provided some hairy moments!
Then I accidently over-filled the power steering pump and the noises went away except if I use the brakes now while steering, the power steering capability drops to ZERO!
I'm 64 and trying to steer this beast in tight places is aging me fast!
truck is a Scottsdale Camper Special and I never intend to run a camper or tow anything major with this truck in the foreseeable future.

Any suggestions?
Thanks!

I did this swap for my 89 crew-cab dually so yes it can be done.

Like yours, my hydra-boost never worked properly & leaked everywhere. I based my vacuum system off of a similar year model 3/4 ton suburban. The brake booster has to be swapped & you'll need the correct pedal for a vacuum set-up.

While it may not be 'as good' as a 100% new
hydra-boost set-up, it works much better than what was there.

Thanks for the response!
Would a vacuum booster for a Scottsdale of the same size and year work?
I already have a new one of those.
What is different about the pedal? Or is it the rod from the pedal?
(I'm proving this is my first mid-70's pick up)

The pin for the pedal is located in a different place (vacuum brakes require a different ratio vs HB). The rod from the pedal can be re-used. For my dually, Hydra-boost was the JB8 brake system. I sourced parts for a JB7 system.
