Jim - you are the man. I now have automatic links inserted into my shopping card page and they update automatically.
To help others in the future, here is general process I used.
1. Took my master page TEMPLATE page and made a copy called it Lef Nav Links Only
2. Stipped out everything but the lines that created the left nav list
3. Created a new PAGE called Left Nav Links Only with html page name left-nav-only-links.html.
4. On the LAYOUT PAGE for the new PAGE Left Nav.... I set the layout to the new page template Left Nav... created in step 1 above.
5. Publish-->Regenerate
6. Verified the new file genterated left-nav-links-only.html in /store directory now only had the left nave links
6. I created a symbolic link on my unix system from the newly generated left-nav...html page to the include directory file. This include file will inserted into the shopping cart template page below. I used the following command. Substitue in your path "ln ..../store/left-nav-links-only.html to the .../shopsite-data/templates/includes/lift-nav-links-only"
7. Went to my shopping cart template and found the area that inserted the left nav links. You will see a generic <td></td> entry. I inserted the following include line [-- INCLUDE left-nav-links-only PROCESS --] and it worked great!
8. I had to edit the link file and do a replace to add /store/ infront of each link as it would be relative to the shopping cart directory. Working on that part to automate.

Hope this helps others. Jim K.
