Thanks for the fast response. The set you linked to was in the Sears store. The screw holes to fasten the base to the router match up perfectly with my older router bases. Unfortunately, none of these bases fit the craftsman bushings. The center holes in 5 of them are too big. The 6th base plate's center hole is smaller. I thought about trying to drill it to the size of the bushings. First I would have to buy a drill bit that large and then I would have to figure out how to cut about approx. a 1/8"x1/16" recess around the edge of the enlarged whole to hold the rim of the bushing. I'm afraid that is beyond my abilities at this time.
