Complete serpentine setup from an 88 k2500 305. All accs other then water pump are included. So ac, smog pump, alt (which appears to be new), and power steering. Will include the fan if you want it. The ac pump is an r12 unit and has a broken connector on it. I have a r134 pump that leaks if you want both. The brackets that bolt to the block are steel, not aluminm like the newer ones. $150. Shipping is extra and I dont really want to ship.
