I went with Vintage Air entire package in my 46, the plus on this is the great heater and defroster that come with it. Also seen several of the AC only under dash units which are great and much easier to install than entire system. Compressor mounting on engine and all the other stuff under the hood is required for any ac and for me with a 6 cyl was the most difficult part. May want to look around on youtube for ideas. Best of luck
