Getting ready to mount a new MK Terrova on my 2005 189 Sport. Anyone had any experience with this aluminum plate? I can remove it but underneath are 2 round pucks keeping me from getting any kind of flat surface to mount to. If I keep the long metal plate I need it to extend to accommodate the new TM plus trying to deal with the height of the tension springs. I guess fabrication and welding is in order. Anyone have any ideas?
