x2. I've had bad experiences with bolts that hold the window glass becoming fatigued and breaking off with very little force applied. I have no direct experience with those bolts on a Koker, but I agree with samhill that a temporary seal should be ok, and that you should allow time for things to go wrong when changing the glass.
