I work for a company called Faxon Auto Literature we are a licensed GM printer and for the first time available to the public are Fisher Body Assembly manuals for 1946-1948 cars.
This set comes with three manuals: One for noise and leak prevention, one for upholstery, and one for welding.
The books sell for $29-$39 each, or you can get a deal on the set of 3.
