1976 Chevrolet K5 Blazer Cheyenne — CKU186F173933

Record at a glance

VIN: CKU186F173933
Year: 1976
Make: Chevrolet
Model / series: K5 Blazer Cheyenne

Evidence status

Verified for exact VIN and the limited facts legible on reviewed VIN-bearing documents. Auction history, seller provenance, later changes, lifetime mileage, and current location retain their separate source qualifications.

Factory documents

A VIN-bearing SPID supports model CK10516 and codes LF4, M40, C60, G80, and Z84. The GM loading plate visibly repeats VIN CKU186F173933 and records 3,300-lb front GAWR and 3,400-lb rear GAWR. Its first GVWR digit is worn and cannot be confidently distinguished in the available photograph, so the earlier 6,200-lb transcription is withheld pending a clearer view. A VIN-bearing Saracho S.A. invoice is dated June 18, 1976 and prints model CC-10516; the CC-10516 versus SPID CK10516 discrepancy remains unresolved. Document images are not republished.

Physical vehicle evidence

Auction photographs document the truck’s then-present condition and later equipment, including repaint, raised stance, replacement wheels, and other modifications. They do not establish original factory condition, and no source image is reused here.

Owner or seller statements

Bring a Trailer and its seller reported original-owner/Mexico-to-US history, a late-2010s refurbishment, a replacement 350-cid crate engine, later equipment, and 60,000 miles shown. These remain attributed claims; total mileage is unknown.

Later research

Exact VIN merges the reviewed document set and Bring a Trailer lot 63,545 as one vehicle. BaT records a $53,000 winning bid on January 15, 2022 after 28 bids. The later 350-cid engine and refurbishment are separated from the SPID’s factory LF4 400 evidence.

Open questions

Resolve the invoice model CC-10516 versus SPID model CK10516 discrepancy; verify the complete original delivery and ownership chain, lifetime mileage, originality of surviving components, and present custody/location. Obtain a clearer full rating-plate or matching certification-label photograph to establish the GVWR.

Evidence scope

This record documents one exact-VIN 1976 Chevrolet K5 Blazer. A reviewed VIN-bearing SPID, VIN-bearing Saracho S.A. invoice dated June 18, 1976, and VIN-bearing GM loading plate support identity and the limited document facts stated below.

Factory and dealer evidence

The SPID supports model CK10516 and codes LF4, M40, C60, G80 and Z84. The GM loading plate visibly repeats VIN CKU186F173933 and records 3,300-lb front GAWR and 3,400-lb rear GAWR. Its first GVWR digit is worn and cannot be confidently distinguished in the available photograph, so the earlier 6,200-lb transcription is withheld pending a clearer view. The invoice prints model CC-10516 while the SPID prints CK10516; that discrepancy is preserved and not silently normalized.

Market history and later configuration

Bring a Trailer lot 63,545 records a $53,000 sale on January 15, 2022 after 28 bids. Auction and seller statements describe a late-2010s refurbishment, 60,000 miles shown with total mileage unknown, and a later replacement 350-cid crate engine. Those statements and modifications remain separate from the factory-document evidence.
