Hello folks, this is my first post probably of many. I have a G3 1652SC its got the front and rear casting decks. I have 1 pedestal base in the middle of the back deck. I would like to add 2 more, I can't install the bases with bolts, before I attempt this I would like to know if you all think using screws will work or will they just loosen up . Appreciate the help and suggestions.
