This item came from a large collection of New Old Stock (NOS) items purchased recently 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 wiper transmission for 1954-1955 (1st Series) Chevrolet truck. Fits left or right. It is in pristine condition and ready to install. Original torn up envelope included. Only ONE available-first come, first serve! GM# 3703856
