I've got a 1964 Panhead for sale. It's got the 64 engine and tranny in a 56 chromed frame with a 48 spring front-end and 58 dash and tanks. There are more details on my site. http://www.purplefoot.com/harley/harley.htm The bike has just been rewired and had the voltage regulator and generator replaced. In good running condition.
Yes the bike is still available. There is information about it at http://www.purplefoot.com. And if you want I can give you phone number of the owner so you can get more specific information.
