Putting new seats in 97 Champion 181 and want to change to 3/4 inch pin mount. Has anybody used the 1.77 inch - 3/4 inch pin adapters from EZ Swivel and if so, do you epoxy them in or how is it done and what kind of luck have you had with it? Is it a good, strong mount? I've had bad luck with the old pedestals getting stuck in the holes.
