i'm trying to get all the fabricating done on the inside of the 53 right now and i was wondering if any one knew of any good salvage yard heat / AC units that are simple and compact that would work good in a rod. i have a rear unit out of a van right now but the only place i can find that it would fit decent is under the seat, which would be neet but it would involve alot of piping and screwing around with making vent controls, and i'm getting lazy. a vintage air system or the likes would be nice but i'm being a tight butt right now
