the window trim on the outside of the driver/pass door, is it the same on other g-bodys in the same time period? also where is a good place to get the K&N 8in cone filter? when i do get the stock air box out and the cone on, what kinda of other tuning, if any needs to be done? I have finally conquered the exhaust leak and it is soundin DAMN good. now time to start upgrading SLOWLY. I need a boost gauge, the gauge that reads boost and Vac are no good? They are like the same price but dont really need the vac side. also who sells the gauge holder in the shade of grey in my 84? phone # would be good. THANKS
