Chevy Truck Identification

1963-65 TRUCK SERVICE PARTS IDENTIFICATION PLATE

The Chevrolet Truck Service Parts Identification Plate entered production, approximately December 1, 1982 on 1963 Series 80 D-M-T (2 Ton) and all Series 80 (2-1/2 Ton) Trucks. The plate is located below the G.V.W. Plate on the left kick panel of Conventional Cab (C-D-E-L-M-U) Models and on the left door pillar of Tilt (T) models. The information which appears on the Identification Plate (see illustration below) is for the most part self explanatory and when used in con- juncttion with the information shown on the G. V. W. Plate and in the Parts Catalog provides a positive means of identifying the type equipment installed on these vehicles. A detailed explanation of the information appearing on the Plate is as follows:
