1976 GMC TKL146Z503002

Record at a glance

VIN: TKL146Z503002
Year: 1976
Make: GMC
Model / series: K15/K1500 4×4 pickup
Assembly plant: Z — Fremont, California (plant code decoded from auction/dealer-reported VIN; no VIN-bearing factory document inspected)

Evidence status

Probable: exact VIN repeats across two Barrett-Jackson lots and a Bird Imports dealer offer, counted as one truck. VIN decoding suggests L-code 350 baseline; no readable VIN-bearing factory options label or build sheet was recovered. Installed engines, named package, mileage and ownership remain unverified.

Physical vehicle evidence

Dealer gallery shows jamb labels, but available pixels do not permit a reliable transcription. The later vehicle photographs show a customized pickup; originality is not established.

Owner or seller statements

Barrett-Jackson described a 396/402 in 2023 and an upgraded 396 in 2024, with “Grand Sierra Package” wording and a C1500 title note. Bird Imports later advertised a fuel-injected 454 and 56,946 displayed miles. These are seller/dealer/auction statements.

Later research

Exact VIN reconciles 2023 and 2024 Barrett-Jackson sold lots and the later Bird Imports offer as one truck. VIN decoding suggests a 1976 GMC K-series half-ton and L-code 350 baseline, but no readable VIN-matched factory options label or build sheet establishes its original equipment or a Grand Sierra package. Current auction pages show sold status but gate amounts; preserved first-party captures report $35,200 and $27,500. Bird’s $55,000 is an advertised price.

Open questions

Recover readable factory labels or option paperwork; verify the auction amounts from accessible first-party results, installed-engine chronology, titled-model wording, lifetime mileage and current custody.

Evidence level and identity

Barrett-Jackson’s 2023 and 2024 lot pages and Bird Imports stock BB503002 each print VIN TKL146Z503002. These are appearances of one GMC K-series half-ton, not three vehicles. VIN decoding indicates an L-code 350 factory baseline, but no readable SPID, build sheet, invoice or certification label has been recovered. The dealer gallery’s jamb labels cannot be transcribed from available pixels. Original options and a named package are not authenticated.

Seller descriptions and sale history

The 2023 Barrett-Jackson description called the installed engine a 396; its fast facts list 402. The 2024 page describes an upgraded 396 and says the truck was titled as a C1500. Bird Imports later advertises a fuel-injected 454. These are descriptions at different appearances, not proof of factory powertrain or of when an engine changed. Barrett-Jackson’s “Grand Sierra Package” phrasing is an auction assertion without recovered factory documentation.

Both Barrett-Jackson pages show sold status, but their current public pages require registration to see amounts. Preserved first-party captures report $35,200 on January 28, 2023 and $27,500 on October 10, 2024; those amounts are attributed to the archived captures. Bird Imports advertises $55,000, an asking price rather than a completed sale. Its 56,946-mile five-digit reading does not verify lifetime miles. Boerne, Texas is the dated dealer-offer location, not verified current custody.

Open questions

A readable factory label or option document is needed to establish original equipment. The installed-engine chronology, titled-model discrepancy, mileage and current custody remain unresolved. No third-party image or private contact information is reproduced here.
