AC be gone

First off I'm a new guy here. I've got an '76 Silverado that I've owned for many many years. I'm starting to work on it and do some fun stuff, but the one thing that I've had a time with is the AC. I don't care to keep it and since I've got the motor out I thought why not get rid of the AC stuff now. So here's the thing I need to keep the heater. If I remove the AC then what do I need to do. Can I use something from a non AC truck to make it work or will I need to go aftermarket or what? I'd like to keep it simple. Basically I need to keep the stock heater defroster still working, while getting rid of the AC. Any and all help will be greatly appreciated. Thanks.

The cabs are different between a A/C truck & a non-A/C trucks. The evaporator housing is also the plenum for the blower motor.
Aftermarket systems dont defog the windshield very well. And have no fresh air setting.

I would leave it alone....You may want A/C in the future.

Re: AC be gone

How much different are the ac & non ac cabs?? I have one I am thinking of swapping to non ac because of mice in the housing,can't get the stink out!!

Re: AC be gone

This is what you want... It allows you to keep your blower motor and heater core but get rid of the ac condenser.

Re: AC be gone

Thanks Flatblack. I'd seen these setups before, but wondered if there were some sort of factory deal. Something to be had in the junkyard? I kinda thought the cabs or really the firewalls were different. So another ongoing guestion is this. If I decided I wanted to use the vents in the kick panels from a non ac truck would they also work? I'm working on putting together a plan for my old truck and to be honest I want to clean up the engine bay, get rid of some of the weight were I can and just enjoy a simple old truck. I have no desire to put AC in this truck. I didn't use it much when I first got the truck and it worked. I like simple trucks. Thanks for the help.
