I have a 1989 Hunter Vision 32 with a broken weld on a stanction post. My question is what holds the 4 bolts thru the base under the deck. Am I going to loose the washer and nuts when backing out the bolts? I have absolutely no access inside unless I cut out the liner under the post. I'm hoping the backing plate (better have one)has threaded hole (wishfull thinking?)Any experiences? Everything I run into with this boat was installed before the inside liner was put up ie holding tank, wiring, stanctions...Tom
