Ok, figured I'd Git-R-Done
took out the rubber thingies in the MT80's. I bought a metal rod and cut them so that it was sticking out the hole about 3/8" polished off the end smooth. then I took some poxy glue put it in the bottom of the hole and placed the rod in. The glue was enough to fill half og the hole when the rod was inserted. I then took my glue gun and finished filling the hole. After a night of drying I took my utility knife and trimmed up the edge smoothly.
then I sniiped off the little knobs from the grill sanded them down even, got my 1/4 " little round magnets and I poxy cemented them to the spots where those knobby's were. Now my grills just snap in place
total cost about $15
