Anyone got experience with one of these? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have what looks to be a dealer installed Ac unit that was in my 72 when I bought it. I'd like to replace the blower and fans and reinstall it in the truck. Any one out there rebuild one or know of parts that would be replacements for the unit. It's a GM custom Mark IV under dash unit. Also any idea how to run power to the blower motor to see if they move? Thanks all

Sorry can't help you on your questions but I would love to find one of those for my ramp truck! That is so cool!

Classic air group may can help you with it.

You could hook some jumper wires off a 12 volt battery to those wires in your photo and see if it turns.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
