Terms of Service
LAST UPDATED · AUG 2026 · REV 7What you're buying
Every product sold here is a digital publication (PDF). You receive a personal, non-transferable license to read it, print record sheets from it, and use it on your own projects. Resale, redistribution, or file-sharing is not permitted — every owner of record is tracked by revision entitlement.
What the guides are — and are not
The guides are planning references: research, method pages, measurement procedures, and record systems. They are not guarantees that a vehicle will run, start, or be road-legal after any modification. Engine conversion involves mechanical, electrical, and legal risk that no document can eliminate. You are responsible for your own build decisions, local regulations, and safety.
No professional-advice warranty
Content is provided as-is for educational planning purposes. We stand behind the research and revise it when evidence changes, but the guides do not constitute professional engineering or legal advice for your specific vehicle.
Delivery & revisions
- Downloads are delivered instantly after payment confirmation.
- Owners of record receive all future dated revisions and errata at no extra cost.
- If a download link fails or expires, use the recover-download page or contact support and we'll re-issue it.
Refunds
Digital products are refunded within 14 days when the file has not been downloaded, or when we cannot deliver what was promised. Full details on the Refunds page.
Intellectual property
All text, layout, diagrams, record templates, and the B58 Swap Bible brand are protected. The chassis plates, M-livery stripes, and plate numbering are part of the publication identity. Personal printing for workshop use is fine; republication is not.
