Original Factory Build Instructions For Your 1958 Corvette
Our 1958 Corvette Assembly Instruction Manual is a direct reproduction of the original documents used inside the St. Louis Assembly Plant on Union Boulevard. Every page is sourced from Chevrolet’s internal build documentation—providing factory-original diagrams, part layouts, torque specs, and fastener guides used during actual 1958 production. This is the authentic factory reference once relied upon by UAW craftsmen and GMAD assembly technicians who built every 1958 Corvette with precision and pride.
Why This Manual Matters
These manuals weren’t created for public release—they were Assembly Line Manuals, used exclusively inside GM’s factories to guide production teams step-by-step. From 1953 through mid-1981, the master copies were updated constantly on the factory floor in St. Louis. What you’re getting is the best available reproduction of the 1958 build blueprint, guiding restorers through every assembly detail from frame to fasteners.

Because Details Matter
Using Chevrolet’s own documentation ensures your 1958 Corvette is rebuilt with factory-level accuracy. At Mid America Motorworks, we’re proud to help you replicate the work once performed inside the St. Louis Assembly Plant—by UAW craftsmen and GMAD assembly technicians who built every Corvette panel by panel, bolt by bolt.
