I was just scrolling though the rock auto catalog looking for some items to add to an order to help justify the shipping and noticed they have reproduction shop manuals both paper and electronic for most models I checked. I have no idea how many years and models they have but they at least have some so its worth checking if you are in the market for something.
For an example 73 Cadillac the printed shop manual is $36, CD $21, USB $24. Fisher body manual printed 2 different vendors, Dave Grahm $14 or Detroit Iron $20. Last time I looked that was at least the ballpark for average used copies of originals were going for on Ebay.
I have no idea the quality, has anyone got anything from those brands before? The Dave Grahm brand also has a sales catalog for 73 at least.
At least dealing with a company like Rock Auto is a little safer than some random person on ebay so that may be a good option for people that are not comfortable with ebay and don't get out to the huge car show swap meets where there are likely vendors selling those brands.
