How much is a new MC?
I had this problem on another bike. Bought an impact screwdriver from Harbor Freight. The machining on that driver was awful. Not much twisting force resulted from hitting it with a hammer. I dismantled it, filed rough edges off of the spiral slots, burnished the pin that rides in the slots with sandpaper. Greased the internals. Soaked the screws with Kroil penetrating oil for days. Watched maybe 3 or 4 youtube videos on how to remove stuck mc screws. Then it worked. Key things are:Make sure your impact driver works wellTake the right driver tip, put it into the slots in the screw heads and tap it in to the screw head with a hammer so it bites in there well.
