Reference Details
- Common issue
- Replacement or visually similar components, added Stage 1 labels, or service-installed parts represented as production-original without matching documentation.
- Confidence
- documented
- Correct value
- Buick parts catalog Stage 1 service-installation list for 1969 includes valve-train package 1394270, distributor 1112016, carburetor 7036730, fuel pump 6470098, and notes production Stage 1 rear axle ratios of 3.42 P.T. and 3.64 P.T.
- Where to check
- Component-level inspection against factory parts-catalog numbers, supported by car-specific paperwork and date/originality review; the catalog list alone does not prove an individual car was factory-built as Stage 1.
