factory AC box.

[dbmx66]

my 84 came factory with AC. its a mud truck and i wont be putting AC back in. is it possible to remove the AC box on the firewall and replace with the standard heater box? or does other stuff have to be changed?

its takes up alot of room under the hood. and gets in the way especially when im adjusting valves which is quite frequent (solid roller cam) and doing other engine tuning.

thanks
