theres a pipe on the firewall just above and behind the motor, that should be for the heater core, but i dont seem to have any hose to mate to it. its at the top left of the pic, the one with rust on it. Any ideas?

 

Should be a feed hose from the left side of the engine.

 

yea i found it lol it was going over the carb and i didnt really look for it too good, lol im an ass but thanks for the reply!
