I purchased my air shocks off the internet. I think at the same place as listed above by Sleepsal. You can't really use shocks off of a 65 and expect any longevity. The 65 shocks mounted on a 64 would mount upside down therefore putting the air bladder in the wrong position. A very big no-no, I am told. I paid a little over $100.00 if I remember correctly. Good luck.
NOTE: By the way, the 64 is a bastard child when trying to find certain parts. I found that air shocks and headlight switches were a freaking nightmare to locate locally or on the internet. I am sure there are more parts that are this hard to find I just haven't broke them yet.
