I'm looking to get a factory/GM service manual for my truck. (I"m not even sure if it's one manual, or a few of them).

Where the best/cheapest place to buy? Am I limited to the dealer? Maybe SDPC?

Thanks.

 

Here is a place that sells them. I don't know if it is cheap but I don't know of any other place.

Helm's Inc.

 

I think you can get the Helms manuals on CD from a guy on ebay. I think they were only $40.00 or so. I opted for the 4 Volume book set from Helms. They've been great help even though some of the part numbers are off.
