My Accessorie falls under reliability, function, and fit. No more taking two v-belts off just to get to one. No more loosing a belt off a pully, or flipping upside down. With the help of Dupli-Color all the brackets, pulleys and valve covers, got Dupli-Color Enamel and 2 coats of clear With the help of Car Craft Mag. I put a "94" S-10 V-6 Surpentine system, with A/C, internally regulated alternator and power steering pump, on a "74" 454ci Big Block motor. It was very easy and as cheap as they say. Around $300.00.
