Where do the lines run, in my 1966 the two hoses ran to the radiator so i had to drain the raditaor from the bottom, then remove the hoses.

Not sure which year model you have, but it must be a later model if the air con hoses hook up there. By law, you cannot just disconnect those hoses and let the freon fly in the air. The EPA gets real excited about that sort of thing. Take it to a competent air con place and have them drain the freon for you. Are you sure those air con hoses are hooked up to your heater box. That doesn't even make sense, since they need to go to an evaporator.
