I installed the classic auto air system(from NPD $895) in my 66. Took about 8 hours to install, no real problems. Could do 2nd in less now. NPD lists an underdash unit for a 67 same price. I'm very happy with mine, and would do it over again.
If the under dash repros work, I don't see why a 65 or 66 wouldn't work. Someone probably has a better answer though. I like the new compressor though, it is much quiter than the original that I have on the other 66. that my .02c
