    One thing still not quite complete on my setup - external braces. How important are those? I've found one that fits from the belt tensioner to the water pump. All the other braces I found simply wouldn't go where I needed them to. Is there a way to make my own, or a supplier of typical ones?

    I supported the back of the AC compressor, but not the alternator. Those were the 2 that came with my set up.

    Thanks, Philip. I'll keep an eye out for a brace like that. I like the spacer too.

    What did you have to do with the A/C lines?

    The spacer and bolt came in the kit. There was a brace for the alternator also but I had to clock it differently for the main terminal to clear the tall valve covers and lost access to the mount hole for it.

    The AC manifold is for a Chevy truck. The tech used it so the valve covers could be removed without moving the compressor. The lines then run over the shroud and connect to the condenser.
    I had it all done at a local AC shop. Excellent work and reasonable pricing. Charged with 134A it will get as cold as the AC in my 06 GMC.

    Haven't tried to solve that one yet. I'm very encouraged that it should be possible. I got a definite "Fssst" when I uncorked the S-10's AC system, so I believe it should work if I figure out how to get it hooked up. I noticed that the aluminum hose fitting from the '78 will bolt right up to the new AC compressor. However, my tall valve covers prevent it from getting all the way down. AND, the compressor is now on the other side of the car.



    Thanks for your pics and notes, Philip - that gives me encouragement. I don't know why I hadn't thought of taking it to an AC shop. That's probably what I'll do.

    <Wups> I was deleting my AC Delete comment while you were commenting on it. Lol. Re-edited my post to put this back in...

    Well, if nothing works out, I also picked up an AC delete pulley.

    AC delete :eek: well for me AC is very important, I am getting old and like my creature comforts.

    The hoses, orifice tube, accumulator, system flush, cycling switch, a little wiring, all labor and a charge of 134A was under $400.

    How did you determine the depth to drill into the head for the bolt?

    Thanks, Ryan
