Though at first, a new person in the GM truck hobby might think all 1960-66 Chevrolet cab trim (only on the deluxe models) is the same. In reality no less than three changes occurred during this seven year body style.
During 1960 (maybe into early 1961) the optional stainless cab side trim on the Chevrolet truck was designed to attach to a long connecting horizontal trim strip. After production began, GM discovered that new owners could easily dent this more delicate trim. When carelessly throwing items in the bed or during fast stops, cargo could hit the stainless. This problem was solved by discontinuing this horizontal strip. The connecting ends of the side trim were then modified to show no evidence of a past attachment (see photo)
Therefore, side trim part# 8768843 and 8768844 as well as the horizontal strip #8768842 are very difficult to locate 45 years later. Most 1960 truck restorers must compromise and use the more readily available 1961-63 side trim.
In 1964, a major change occurred in the construction of this cab trim. Chevrolet followed the trend of other new vehicles and also began using aluminum trim. It was anodized to keep its shine and the production cost was less. It required lower pressure to be stamped as compared to the previous stainless steel. Thus, the tooling lasted much longer.
