Make: GMC

Evidence status

Verified exact VIN from photographed GMC identification and GM certification labels in the AutoHunter gallery. The May 1976 certification ratings are readable; factory engine, transmission, paint and options are not established without a SPID or build sheet.

Factory documents

AutoHunter gallery images 055 and 056 show the GMC metal identification plate and a GM certification label bearing TCL146Z510768. The latter is dated 05/76 and lists 6,050-lb GVWR, 3,250-lb front GAWR and 3,580-lb rear GAWR. No SPID, build sheet or factory invoice has been read.

Physical vehicle evidence

The gallery shows orange paint and Sierra Grande 15 badging on a Stepside pickup. Appearance does not authenticate original paint or factory options. The listing’s Sierra Classic wording conflicts with the photographed Sierra Grande badges.

Owner or seller statements

The seller described a replacement 350 V8 installed in 2025 and a replacement TH350 automatic. The five-digit odometer showed 9,885 and reportedly rolled over. These are later configuration and mileage statements; lifetime mileage remains unknown.

Later research
