keeping heat and a/c on sfbd 99' escalade

Need some help on figuring out how to keep my factory heat and a/c, well a/c is not as important, but still would like to have it on my stock floored 99' escalade. I am running 24's on it and all that good stuff with tubular control arms and all, just wondering how to keep the heat mainly, dont really wanna run a hot rod style heat/ac unit. any help would be great

You shouldnt have a problem keeping both. All you need to do is tub the heater box behind your firewall tub. Youll lose the recirculate option but it isnt important. Im doored on 35 series 22s and that is all I had to do. 

what about the blower motor and things coming out of the firewall?? You got a pic or anything by any chance??
