Keith has some GMC information on his website.

If anyone has a GMC manual and you want to scan it and have Keith host it, contact him for scanning "specifications".

If anyone has has a GMC manual that you do not mind Keith scanning, contact him about doing this.

Here is what Keith sent to me yesterday:

"All the hard copy manuals I have received, I take them apart carefully, scan and then rebind them. All the manuals I have here have been done that way. Several folks have loaned manuals to me and I make sure they know what I will do to them. Most cases, the manuals are returned in the same condition or better. This is a time consuming chore, but sometimes this is the only way to obtain the information in the manual if I can not find and buy it elsewhere."
