Thanks, Mike that looks like the info I need. I found a 3 gallon tank from Firestone that measures 20" x 7" for 35 bucks. I have the compressor on the front quarter panel under the driver side battery. The little tank is on the driver side bumper bracket. The horn is under the radiator, zipped tied to the cross member. So far so good, but I'd like to work up a permanent bracket.
