my del sol has been parked outside for awhile and ima start messin with it a little bit. it has the stock D15b7 motor and the header is pretty rusted. i was wondering what i can do to take off that rust and make it look semi nice. i see ppl do it all the time on the B-series headers. and also if i were to take out my air conditioning would i be able to put it back? yes some dumb questions but when i serach it shows how to take it out. TIA-
