A/C box?

[thrtsxchambers]

well the stock components seem to flow fine and the ducting is good. I think the only thing wrong with it is the controls, when I first got the truck I ripped everything out around the gauges, radio, a/c controls and the controls had alot of rust on them and they don't slide very well. I think recently something on it broke b/c it is stuck on defrost, I have not really check out the components under the dash but they seem to work.
