THERE IS AN EARLY AND LATE STYLE REAR HUB (D-CODES 26-112 / 26-112Z) AS SHOWN BELOW. AS STOCK IS EXHAUSTED OF THE EARLY HUBS THEY WILL BE PLACED IN A “C” (COMPONENT) SUPERSESSION SO THAT A NEW HUB AND ANY ADDITIONAL PARTS THAT MAY BE NEEDED ARE SHIPPED AT THE SAME TIME. WHEN GEPC VIN LOCK IDENTIFIES AN EARLY PART NUMBER, AS WITH ALL “C” (COMPONENT) SUPERSESSIONS, ORDER THAT PART NUMBER. DO NOT ORDER A NEWER PART LATER IN THE SUPERSESSION CHAIN. IF YOU ORDER THE EARLY PART SPECIFIED BY THE VIN, A NEW PART AND ANY ADDITIONAL PARTS THAT MAY BE NEEDED WILL SHIP. IF YOU ORDER A NEWER PART, JUST THE NEWER PART WILL SHIP. NO ADDITIONAL PARTS THAT MAY BE NEEDED WILL SHIP.
