I recently retired my classic 12" lx 200. I had it mounted on the a super wedge with three 5/16 bolts. My new 12" lx 200 acf has a larger bolt 1/2"? on the top position of the drive base. The other two holes are 5/16. The problem is the top slot on the wedge is open to accept 5/16. Has anyone just drilled out the top slot to fit the 1/2" bolt? Do the other holes line up with the old lx pattern?

                          thanks
