    I have a 1974 Chevy Truck with a 250 inline 6 and a 1 brrl carb. It is in desparate need of rewiring and is missing several vacuum components. Would greatly appreciate any assistance in finding these diagrams. Thanks!

    I have the wiring diagrams for '73 in the GM Factory Service Manual. Do you have a fax# or maybe I can mail a copy to you. It should be about the same in '74.

    You wouldn't happen to have diesel wiring diagrams for early-to-mid 80's GM's and 88 (newer style) GM's would you?
