In an earlier post a forum member suggested the Helm website for manuals.

I was looking to see what is available for the C1 and this is what they show. (no pictures)

Media: Paper Language: English Part #: ST12 Models and Years Covered More than 3000 pages of repair instructions written by General Motors, this is the original manual. It contains Diagnostic Information and Procedures, Schematics and Routing Diagrams, Component Locator, Repair Instructions, Description and Operation, Specifications, and Special Tools and equipment. Service information on HVAC, Body & Accessories, Restraints, Steering, Suspension, Driveline/Axle, Brakes, Engine and Transmission/Transaxle.


I already have and use a manual marked ST12. It has a drawing of a vette and a sailboat on the cover. My ST12 is not even close to 3000 pages. I called Helm and the gal assured me theirs is 3000 pages.

Is anyone aware of different ST12 available. Is the one sold by most corvette supply houses a condensed version of this one Helm is selling?

Any info on this subject would be appreciated.

So far as I know there is only 1 ST-12. The one I have is 30+ years old and is just like the ones currently sold.

The Helm description is wrong, but the title is correct - "1953-62 Corvette Servicing Guide". It does NOT have 3000 pages - it's about 5/8" thick, maybe 150-200 pages, and all the Corvette resto parts houses sell it for about twenty bucks (Helm wants $40.00 for it).
