Zach,
I found the mounting plate for your question: It's a Universal Mounting Plate (Adapter Plate) from Craftsman:
P/N 9-26479 Craftsman Professional Large Router Adapter Plate
• Molded glass-filled polycarbonate plastic adapter plate mounts most non-Craftsman routers to the 171.264630 and the 171,264640 Professional Router Tables
• Easy to follow instructions and mounting templates supplied
• Adapter plate mounts to the router table using fasteners supplied with router table
• Fasteners for mounting the router to the adapter plate are not included and must obtained separately
IMPORTANT NOTE: The drilling and the countersinking of holes in the adapter plate are necessary in order to mount the router to the adapter plate. The screw heads must be slightly below the top surface of the adapter plate.
AND your other question of the fence:
Also from Craftsman P/N 9-26472 Precision Router Table Fence Assembly
• Mounts to all Craftsman Professional Router Tables
• Extruded aluminum fence is fully adjustable measuring 4" high and 27" long
• Fence opening is adjustable for different size router bits providing greater support
• Exclusive "keyed"jointing feature straightens workpiece edges for gluing
• Fence assembly has 2-1/2" diameter dust port for wetJdry vacs with 2-1/2" diameter hoses
• Clear see through guard allows viewing of the work area
• Incorporates T-slot design for mounting feather boards
Your Router Table is a Craftsman M/N 171.264660 Professional Router Table
171.264630 (without Floor Stand)
171.264640 (with Floor Stand)
Hope this helps.
