I couldn't live without te "Big 3"....Assembly Manual, Chassis Service Manual and Fisher Body Manual.
The Assembly Manuals were originally made for one purpose....to assemble the 1971 Cutlass (and all derivatives). Once done, they moved on to the next year/model. The ones I have seen...all from ebay....all from different suppliers...are all about the same. No important missing pages...no real missing info. But they ARE invaluable.
JMHO.
