A Service Parts Identification label can give an old pickup a more detailed paper trail. The useful part is seeing exactly what it says, then comparing that with the other documents and the description of the truck. These two examples come from Texas Trucks and Classics listings.

A closer look at a 1977 C30
The dealer identifies the first truck as a 1977 Chevrolet C30 Silverado. Its photographed SPID and a separate metal identification plate both read VIN CCL347Z156789. The SPID also prints model CC30903.
Among its entries are LS9, “V8 ENGINE – 350 C.I.”; YE9, “SILVERADO EQUIPMENT”; and ZW3, “SINGLE REAR WHEELS”. Those few lines put specific document wording behind parts of the dealer’s description. They also give a future researcher something precise to compare with other paperwork or a physical inspection.

A different question on a 1984 C10
The dealer’s 1984 Chevrolet C10 Custom Deluxe listing describes an automatic transmission and a utility bed. Its SPID, bearing VIN 1GCCC14H1EJ106307 and model CC10903, includes MM3, “3-SPEED MANUAL TRANS”, and a “FLEETSIDE BODY” description. The first character of that body-option code is faded: the reading remains [E/F]63.
A separate camper-loading label carries the same VIN, although its print is faded. Keeping these observations together preserves a useful question about the truck’s history. The photographs and listing do not establish when or how the advertised configuration came about, so neither account should be rewritten to make them agree.

These are selected readings from photographed documents. The year and model descriptions above follow the dealer’s listings. Matching VINs link the photographed identifiers; they do not authenticate the labels, establish original attachment, or verify the equipment on either truck today.
