Service Manual

[97z71]

Can any of you guys recommend a good place for me to get a in depth (not Chiltons type)
Service Manual like the use at the dealer by professional mechanics.
My truck is a 97 GMC 1500 Z-71 Extended Cab 4x4 with a 5.7.
Thanks in advance for your help.

I agree that Helm is the source for exact duplicate factory manuals.
