Open questions

Establish artifact authenticity, manufacture date, original trim, original-component and original-finish retention, lifetime mileage and later custody. Retain literal W/BASE 1315, the shortened 41L paint wording and the full-upholstery transcription hold. Reconcile label solid-paint/green-vinyl information with the dealer description without treating later presentation as factory proof.

VIN and historical ratings

The Streetside Classics Ft Worth listing, stock 3492-DFW and ClassicCars CC-1228041, identifies this GMC pickup as TCL146S504278. The full VIN is clearly readable on both the photographed GM identification/loading plate in image 67 and the Service Parts Identification (SPID) label in image 68.

The metal plate lists GVWR 5,300 lb, front and rear GAWR 2,940 lb each, and literal CWR 517 lb. No manufacture date or federal conformity declaration is visible on this piece. Its historical ratings do not establish present safe loading capacity.

SPID observations

The SPID records model TC10903 and literal W/BASE 1315. Selected equipment rows include LS9 with 350 C.I. engine wording, M40 with Turbo Hydramatic wording, A52 front bench seat, C60 air conditioning and E63 Fleetside pickup box.

The label prints ZY1 “SOLID PAINT” and 41L “41 SPRING GREEN-SOLI”, retaining the visible shortened ending. Its 44V row has green-vinyl wording; a complete upholstery-prefix and ending transcription is held. The dealer describes the pictured finish as deluxe two-tone and an original color combination, and describes a partially restored black interior. The label readings and dealer account remain separate; they do not prove that the present finish or upholstery matches the original configuration. Original trim level and component retention are not established by these selected readings.

Listing account and limits

The dealer described a Sierra 1500 long-bed pickup with a 350 V8, TH350 three-speed automatic, 12-bolt rear axle, air conditioning converted to R134a, replacement-style audio and supplementary gauges. Its originality and factory-equipment descriptions remain seller statements. The listing displays 91,482 miles; lifetime mileage and odometer continuity are unknown.

The archived asking price is $17,995. The page now marks the vehicle sold/unavailable but does not establish a sale date or paid amount. Ft Worth, Texas is the historical listing location, not verified current custody.

Review scope

All 71 exposed stills were screened. Photos 67 and 68 were examined in the linked 1280×960 versions. No separate buildsheet, invoice, order form or readable dated certification label was identified in that set; no video was assessed. This is one dealer/syndication source family. Artifact authenticity, manufacture date, original trim and component retention, later custody and lifetime mileage remain unresolved. No source image or private personal detail is reproduced.
