Best A/C system for a 66 fastback

I have installed the Vintage Air system in a customers 65 FB. Not very impressed. I found a thread in a search that asked about A/C in a 70 and the recomendation was Classic Air. I looked over their site and pulled down the instructions. Looks like an easier and cleaner install than the Vintage system. However...

I spoke with an A/C vender at All Ford Carlisle this year (he sold all the different brands) and he said the Vintage system was the easiest install. Hmmm.

I thought the engineering of the Vintage system was lacking. And the tech help response to a question about hose routing was "no one has ever asked that in 10 years..." Their template shows the hoses going under the battery tray through the core support just under the stone defelcter. I had to raise the battery tray. "Under" the tray is outside the eng compt. They say thats not true? It does work great. Ice cold air, just felt it was a tough install.

So, if you have installed an aftermarket A/C system, please let me know what you liked and didn't like about it.

12sec67, thanks. I think I am going to try the Classic system. I had a bunch of other problems with the Vintage system. The lines attach to the evap inside the blower hole, not outside. Real pain under the dash. The evap box did not line up with the mount at the corner dash. Few other things. And the comp bracket we got we had to severly modify.

Anyone else have any thoughts?

66runt, thanks! Great info. I think I have my decision.
