Hi hitnailonheadwithhammmer
The one you will need to order is the 23134 BUT for the 17543 it will also take on the Porter Cable base plates that's to say the base on the router is drill and taped for the Porter Cable setup as well.
And your New Craftsman router #17543 will also take the new Porter Cable motor...as well..
23123 Router Table Plate for Craftsman Standard Routers In Stock $49.99
23134 Router Table Plate for Craftsman Plunge and Heavy Duty Routers $49.99
