zach,
The owners manual describes the template adapter on page 17.

without seeing it, I can't tell which size template guides your router uses. Two 'standard' sizes are available quite reasonably priced from lee valley at the following link

If I get to lowes this week I'll see if it fits a standard PC guide, assuming lowes has one on the shelf with the template guide attachment on it.
As a last resort, you can always get a aftermarket plate like the one from Oak park that accepts the larger template guides. They're on sale right now....

Hope some of this has been helpful
