In my surfing over the web I have run across a number of sites which have parts and/or shop manuals. Here is a list. I do not host most of these, they are just links to other web sites. If you find a web site with parts or shop manuals on it let me know so I can list it here for everyone.

I usually don't remove any links, once I put them up. I have had some dead links become active again after being gone for as much as a year. If you hit a dead link, try it again in a minute, hour, day or so, sometimes even a week or two or more.
