sooo whats the problem? there will most likely be a pocket to glass in and some hardware to thru bolt and a foothold with hardware attached to be bolted in to the pocket and hardwqre on the hull? I don't see why there would be any problems other than if they were to come loose or get broken off, which would seem pretty hard to do.
this would seem to solve the problem of a first time install where the person is unsure of just exactly where they want the foothold. wish I had thought of it.:beerchug:
