Hi, I've got an '89 K5 that I'm looking to add air to, I would like to mount a tank have the compressor fill it. I read the review on the York compressor, but I'm looking for a more inexpensive way. I found an air compressor from an '86 Cadillac (air ride suspension) for $12 at the local yard. I haven't had a chance to rig it up and see what kind of PSI it will put out, I've read it'll put out 60-90 but couldn't verify that. Have any of you had any experience with a compressor like this? I'd like some input, thanks.
