I am trying to replace a winch strap (currently some type of nylon rope) with one of those thin flat straps. There is no way to separate the disc (the thing that the rope winds around) in order to tie on the new style strap which has a loop on the end of it. Do I have to drill a hole through both sides of the disc and mount another bolt through it? If this is the case, what size bolt should I be using? The boat I am towing weighs approx. 2000 lbs. Any advice is appreciated.
