Air conditioner delete.

I'm not sure if your going into the heater/ac box or not,but this is what I've done on a couple of my ac trucks.Most of the ac components were missing anyway,so when I replaced the heater core,I removed the evaporator & sealed up the holes where the ac hoses came out.I got way more air flow in the cab now,I didn't care about ac, but wanted a decent heater & it worked great.
