Dan Wesson take down?

[SCORPIO]

OK, new guy here so don't beat me up too bad for this stupid question. I'm looking at the manual for my new to me RZ-10 and it shows using an allen wrench to remove the guide rod. On my gun, the end of the rod is knurled (sp?) with no wrench flats. So how do I remove the guide rod to take down the gun?
Also, they make reference to a bushing wrench, I don't have one of those. Where can I get one?
Thanks
