I need the Shop Manual for my new toy. It must be GM Form Number ST330-87K . The number is on the front cover in the lower right hand corner at the bottom.

You've probably already seen this and I can't find a number on the front page:

The link has ST 330 87 but not the K

Thanks for the tip. There is some good info in that manual too, but since I don't know much about the Chev paper, I'm going by what an expert told me and that was that I need what's called the Lt Duty CK manual, Form No. ST330-87K. I appreciate your help and interest. Thanks.
