I don't know if all here are aware of this good resource . I'm still looking for a 1976 GMC or Chevy shop manual , I couldn't find it there .
Nate, I'm guessing that you'll have to get the 1974 GMC truck shop manual and the 1976 GMC truck shop manual supplement, both of which I found hard copies of online for sale.
FSM's THANX ! . The deal is : I'm not plannuing to keep this truck after this one job (yet anyways) so I don't want to pony up $60 for a pair of books I'll lot use again , I have thousands of Tech manuals now I don't use often . I -know- there's a greasdy , dog eared shop copy out there just waiting to be tossed out or sold for $5 . , i just need to find it . I hope to-night to yank the driveline off and the manifolds too .
