Just ordered one of these for my '97 K1500, figured for the price it was worth the gamble. If anyone has any experience with these, please feel free to chime in. Otherwise, I'll post when I get it in a week or two. The printed manuals were running at $100 or more for worn, beat up sets for the two volumes.
