Universal cross-sell
The multi-guide frame-off project bundles have retired — the marque-agnostic Master Checklist v2 now sits as the authoritative pair-bought-with-every-guide reference. Thirteen phases, 250+ line items across Pre-Restoration Documentation, Disassembly, Frame & Chassis, Suspension / Brakes / Steering, Engine, Transmission & Driveline, Body Prep & Paint, Exterior Trim & Brightwork, Interior Restoration, Electrical System, Engine Bay Detailing, Final Assembly & System Verification, and Concours Prep & Judging. New in v2: every year / marque-specific task cross-references to its matching single-year guide, so the master checklist stays marque-agnostic while year-correct casting, part, and fastener detail stays one click away. One printable PDF, instant delivery.
