Who files this
The B58 Swap Bible is a digital planning reference and build-record system for BMW B48/B58 + ZF 8HP swaps. Each paid guide is scoped to one chassis family. It is not a wiring harness, not a parts kit, and not a promise the car will start.
Jeremy files the desk. The inbox is a real person: LegendB4858@gmail.com. There is no call center and no invented founder story.
What you actually buy
A PDF. Instant download after Stripe checkout. Ten chassis programs on the shelf, a 58-page E9x planner, and a crew bundle that is the E9x guide plus the planner. Owners of record get dated revisions and errata at no extra cost.
Sample pages are public. Refunds are 14 days if the file was not downloaded, or if we cannot deliver what was promised. Lost the email? Use the recover-download page.
What we will not claim
- Universal fitment. Chassis, body, drive, engine variant, 8HP unit, and controller path all change the job.
- A start guarantee. A planning reference cannot certify a project car.
- Invented customer stars. Five lifetime orders is not a review wall. The honest page is Reviews.
How a chapter is supposed to work
Identity first. Then the controller path. Then measure before you buy parts. Then commission with a written record. If a page cannot tell you the next decision or the stop point, it does not belong in the paid file.
