    I'd say it is air pressure because I have seen C-70 trucks with the same gauge cluster in them

    I like that 'fuel' under the 'tach' setup. Anyone know what year/models had a cluster like that?

    That's definitely out of one of the "big" trucks, I believe the one I grabbed a setup out of like that was early 80's.

    77 and newer C-65's and C-70's had that gauge cluster. And that air pressure gauge is for a truck with an air shift 2 speed rear axle and hydraulic brakes. If you didn't ask chev about the how the axle shifted you got the air shift and air compressor for free...but spec air brakes and you got the **** charged outa you and they told you how difficult it was to put an air compressor on that truck, guess how I found out:mad:

    Dont see why not.. wonder if its mechanical or electrical?

    If elec, all you should need is the correct sending unit. If mech, a line needs to be run to the gauge.

    The air gauges are mechanical they have two fitting that come out the back I made a jumper hose to make sure they would work for a buddy and they work awesome. There are 2 needles on that gauge and 2 air fittings on the back. I would like to see someone use them I will in my 73 blazer eventually but where I can get them wants 100 bucks and I need to put that 100 bucks elsewhere right now.

    If the seller wants $100 for just the air gauge you can get a gauge from a semi that will work, standard 2 and an 1/8 inch gauge for a lot less....

    it should... but you need to check a couple guages:
    OIL: mech (73-77/78) or electric (post 77/78)
    VOLT: voltometer or ampmeter... i dont think its a "plug and play" thing, but im not sure
