Going hydroboost

Here's how I mounted mine. The back of an old vacuum booster makes a good hydroboost mount. Found an old (1979)Toyota mini truck booster with the same pattern as a TLC, cut the back off with a die grinder. The piece is now a mounting plate with studs. Then I modified the center hole to mount on the hydroboost. The Hydro boost bolts up to firewall without any mods.

My hydroboost came off a 85 Caprice wagon, but is identical to what I've seen on Chevy pickups.

I haven't got to doing the hoses yet.

all of the tech articles I have seen say to build 6an fitted hydraulic lines .Where do I buy the adapters to mate to the box and hydro unit?

I did a google seach for power steering fittings and came up with a bunch of places. Unfortunately, with hydro boost, you need 4 o-ring fittings at $12-$16 each.
 
If your lucky enough to have old hoses from the donor vehicle or if it's a junkyard take out and old hose ends are left on, sometimes the old ends can be reused. In the past I've ground the metal covering off the rubber hose ends, cut off the rubber part and found the barb fittings in good shape. I slide my new hose over and use A/C style screw clamps.
I've been able to do this on the GM vehicles I've worked on.

This will work only if the Gm end and Toyota ends have the same size hose ID. Otherwise I guess we'll be shopping for new fittings.
