Nipper,
Yes I can do this, but the problem is with the inability of these new ones to be mated to the fish holder/base without covering the top of the holder with plywood to screw into. I'm trying to find someone who has the original Wellcraft track/hardware for the lounge seat, then I can make a custom seat to fit the track. With my current set up (or a setup from any seat manufacturer these days) we have to forego using the cover for the fish box. Using these new seats takes away the intended luxury of sliding the loung seat back on its track and putting a fish (beer?) in the underneath storage. Even if I could get pics or specs of the original lounge seat hardware I could reproduce it. My quest continues, thanks for the reply.
