I am about to pull the trigger on an Ultrex for my 2017 Sabre. It currently has the factory installed Fortrex. I lifted the Fortrex pedal to get access to the underside of the Fortrex mount and was surprised to find solid gelcoat! There is no hole (and cover plate) under the pedal. Both my other Basscats had it.
How do I install the Ultrex mount without the access hole? Do I have to buy a giant holesaw and cover myself? If so, what size saw and plate?
