HH, I've used the Old Air hurricane kit in my 54 truck. Installation was straightforward and performance has been outstanding. There product and finish is of good quality. I went with Old Aire instead of the Vintage unit because of the ease of getting at the main hose connections which are on the engine side of the firewall. The advantage of this is that you don't have to wedge yourself up under the dash to make the final connections. The disadvantage is that the connections are very visible on the firewall.
They provided all the necessary mount brackets for the compressor to engine as well as the bracket to mount the alternator or PS pump above the compressor. Their hurricane system has a 3 speed motor which gives you a "Hurricane" volume of air to do the initial cab cooling and a low speed which allows you to smooth your hair down and carry on a normal conversation. They provided perfectly formed hard lines from the condensor through the core support that required no core support alterations. The underdash evaporator used 2 existing holes, from the stock heater that is removed (I got their kit with the included heat), to properly position the unit and required only 2 additional 1/4" holes in the firewall. They even included the insert needed when you shorten the stock glovebox and the cable controlled shutoff valves for the heater. All hardware was included and the drive belt was the only item not included in the kit.
I would buy the kit again if I wanted to air condition another project truck. There are some pics of the install in my webshots album.
