This item came from a large collection of New Old Stock (NOS) items purchased from a Chevrolet Dealership in California. These parts have not been offered for sale in the last 35 years. As you view our online catalog you will see many of these items listed for sale. Each item is unique and we cannot get more of them. These are new GM factory original parts - not reproductions. This is a NOS arm rest mount adapter unit for 1961-1964 Chevrolet forward control truck. It does have surface rust and will have to be cleaned up before it's ready to install. Original box and instructions included. Only ONE available-first come, first serve! GM# 988410
