[C10 - C90 Bill]

A factory Air Compressor would be nice, but if you just need one for your Air Horns, I would just go with an Electric aftermarket one. Although the nice ones can be a little pricey. I got an original set like the ones on your truck at a swap meet a few years back and tested it with my little 1 Gallon Compressor at about 100 psi. They sounded perfect at 100 lbs.
