Ok guys heres the thing. Im into real clean and simple when it comes to my rides. Im shaving the firewall on my S10 truck and Im swapping the brake booster to a hyrdaboost system and hiding it behind the dash. I also want to hide the a/c heater box behind the dash. Is there a stock a/c heater box I can use or am I going to have to fab something up? I would like to use something thats already made if possible, modifying it would be alright though. So anyone have any recommendations?
