I put a Vintage Air system in my 46 a few years ago, was quite a job but a good learning experience. They do not offer a 'KIT' for this series truck so you'll need to fab every bracket, hoses etc. Got some excellent help from a good friend, engineer/fabricator guru, fabed mounting bracket for the compressor in the generator location and then used an alternator above the gen. Used a single belt set up then a smaller one up to the alt. What I'm most happy with is finding some space just under dash trim for VA's long slender vents and controls, expensive bits but really worked out well with such limited space. I'd sent in several photos of this job to the Stovebolt gang but it never showed up on the site??? You can send me a PM and I'll send you some pics if needed.
They list a kit for 54 I believe.
