Anyone know of a good A/C system for a 52'. Recently I have been looking at heat/cool/defost units from Vintage Air and Classic Auto Air. I don't want to go spendin one grand on an A/C system when I'm not sure how well it performs. I don't really need a underdash vent system that fits the stock contour of the dash because I'm going to make my own underdash panel. Any suggestions would be appreciated.

Thanks,
