Looks like a great old work truck 71swb4x4, and probably just what you need for your job.
About the hydro boost brakes, I just never worked with them before and don't even know to where from where the hoses should go. Mine came from a 76 C-30 van (motor home), and did not get to see the actual hose runs.
I just took out a pretty new booster and dual hole master cylinder (MP Brakes Co.) that I put in when I put in the 78 disk brake parts (with all new seals and bearings) because I never COULD get it to work right (it will end up on Ebay one of these days).

If you are pulling off the front sheet metal from the truck, would it be possible for you to email me a picture of the rubber hose runs for the brake system?

I am also going to put the rear end from the 76 in as the brakes are MUCH wider and will match up to the 350/350 from the same donor truck.

HERE'S A LINK to pic of my rig.

Thanks,
Joe
