That seat heater link will come in handy! Wife wants a 2 seater sports car, new or old, I want an old one for her, but she had to have two things - air bags and heated seats. I was worried about a pain in the rear having to swap late model seats in, but that solves it! Now the air bag thing... Fun, fun, fun...

As far as the heater, I currently have an email in to Vintage Air, asking their sales/tech guys if their truck heater kit for our trucks comes in any options for larger cores with more rows or anything, as I explained I MUST have a heater that can heat my panel truck like my 89 Suburban heats. I'll post my results. My concern was that they are just mainly designed around a small pickup truck cab, and that their design would limit the effectiveness for a panel/burb.

As for the standard vs deluxe heaters, can anyone confirm that the deluxe heater has a larger heater core coil area or more rows of tubes???? I wonder if there's any way to swap in the deluxe into a standard heater, if so?
and maybe I can get all the ducts and vents off of a deluxe setup (or aftermarket vents) and possibly run ducts off of my standard heater???
If I go this route, I would definitely want to upgrade to a 190 degree stat to get some extra output. If this is the case (I could get a larger/better core), then I might be able to get off easy!
Otherwise, the vintage air or old air or whatever retrofit AC kit (minus the condenser/compressor/drier/etc - just using the heat parts) might be the ticket, as it is designed to fit into the same spot on the firewall and interface with our controls. IF I can get any larger coil, again! Might look into the coil size on my 89 Suburban and see if I could in any way make that work in my 62, even if I had to get out some copper and braze/solder new stubs out at different angles (I do hvac, so brazing on coils is a daily thing for me).
