You can download it from the Smart Parts web site.
Can't give an actual address to the page as the new site is Flash based, but i can tell you where to find them on it.
Go to
http://www.smartparts.com
Click on 'Support' at the bottom right.
Click 'Manuals' on the left
Then chose which one you want to download (for 05 shocker use SFT Shocker)
you will also find the manuals for the boards etc too.
Enjoy!
