Ardun, I used vintage air, I got mine from speedway, reason I did I could get it next day. I would use under the dash that crosses under the steering column and to the right, also I would get the heat and air combo unit. Also you need to use a insulation pad on the floor up to and including the firewall, any other questions please ask., send me your email to
[email protected] and I will send pictures. the unit put out 47 deg when installed.
