I just wanted to pass on a source for a pretty good shop manual that covers CUCV's and 6.2L engines. I looked all over the place and could not find a real GM/Chevy shop manual for less than 60-100 bucks. While looking around Ebay I came across ( Filmsdocs) They have CD manuals for M1008,9's,and my toy M1010's. The manuals go for 6-8 bucks, and after I recieved mine I was very impressed with the amount of material on the CD. Typical of military manuals it has good diagrams, and lots of spec's.
If anyone is interested in a CUCV manual or just some better info than Haynes/Chiltons provides for your K10-20-30 check them out.
