Which 75 service manual?

[ron350]

I have a wiring diagram for a 1975 C & K truck that I Xeroxed from a manual that I can no longer find. The diagram was on two facing pages and at the top of the page says 1975 C & K Models (page ) 6-148 and 6-149.

Has any one ever seen this 1975 factory service manual with a wiring diagram on 6-48 and 6-49. I have several pieces of Chevy truck manuals from 1973 back and none of them have complete truck wiring diagrams?

The strange pat is that there is Xerox bleed through from page 6-147 and 6-150 and there is wiring diagrams on those also.

So if any one has this manual I would like to purchase copies of pages 6-148 and 6-149.
