Vintage A/C product... whos got one?

[ky-donzi]

Hello

Well I am far away from needing a vintage a/c unit, and from what I have read it is one of the best. For those of you that havnt seen my build, I am building a 4bt cummins 61 GMC.... My question is my truck is equipped with the deluxe heater (I believe that is correct) it is the one that has the huge box in the engine compartment with the core in the engine compartment...anyway my question is, When I buy the "vintage Air sure fit" do I discard all my gm heat stuff... and get rid of the big box in the engine compartment?

Thanks in advance
