Awesome score, paid nearly $175.00 for mine but includes all volumes as well as all the suppliments, updates, TSBs, etc...
Does your driveability manual publication number end with 2?
2 indicates the second (latest revised) edition.
I bought my full set of '95 C/K Service Manuals from helminc several years ago, and have been posting bits and pieces ever since. If you need anything specific, LMK..
For a while, alot of the sites (including DP) wouldnt permit posting of "copyrighted" FSM materials in fear of legal ramifications.. Note that is NOT against the law to share "copyrighted" material as long as it is for "educational purposes" and/or noone is profitting from it.. Although I suppose you could PDF the entire thing, I suggest limiting the publically shared material to no more than is needed to make the point, or achieve the purpose..
Fair use of Copyrighted material
IMHO, my 1995 C/K Truck Driveability, Emissions, And Electrical Diagnosis Manual (GMT/95-CK-2) is worth its weight in gold... To say it "Pays for itself the first time" is an understatement.
Note the diesel (specific) section is the back half of the manual... Takes a bit of getting used to using and navigating GM service manuals, FWIW "diesel" should be noted at the top of the correct (applicable) pages.
FWIW. Im told the '94 manual (EFI driveability specifically) contains numerous technical errors. Even the first edition of the '95s driveability manual was completely replaced with GMT/95-CK-2, the last most updated OBD1 revised edition.
I suspect most changes, revisions, or errors were in the electrical section given the number of additional manual suppliments and updates I have to further complement my own full set (including most TSBs)....
Anyhow, sure you'll get 10X's your moneys worth and then some from them..... enjoy
