I have a broken Vetus coupling bolt that I need to replace. Figure I will replace all the bolts. I can see how the nuts of the bolts can come off easily, they being on the engine transmission side. However, the heads of the bolts are on the C drive side, and there is not enough clearance to get the bolts out. Another post suggested hacksawing off the heads of the bolts. Wondering what you think about that?
