I just happen to be looking for the same thing and found this;
http://www.hartvilletool.com/product/11203

Check it out, uses Porter Cable bushing and lock nuts.

To be perfectly frank, I am really lost.I have two routers. Both Sears
1. model 315.175040
2. model 315.275051
I can't find a router guide bushing kit that will fit either one. They do not have 1 1/2 inch holes.
Where can I find sub bases that will fit either router?
