The kit I got from GM Canada was 90% photocopies of American-built trucks using their codes. There was a lot of info which is in the shop manual. to me the only worthwhile item was one sheet of paper addressing my truck. When and where it was built and delivered. Nothing about to whom. Then it told me it had a 216 and how many trucks with that code were built. IMHO I would spend my $25 or is it $50 (plus tax) on something else.
