HOW TO DO ? A/C Refrigerant Conversion??? HELP! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got a 250 cubic inch straight 6, with A/C. I've seen the conversion kits at the parts stores with the new a/c refrigerant and a few fittings and such, but: Don't I have to evacuate any OLD refrigerant out of it first? Now, I have never had the A/C work in the 7 or so years I've owned the truck, but I guess it could be possible there might be a tiny bit of the old stuff inside. I'd appreciate any tips on this, many thanks!!!
