I have a 1998 Grumman 16' stick steer boat. The boat came with the plastic seat pedastals that double as livewells. Over the years they have cracked and I can't find a replacement anywhere. I'm just curious what it might cost to have them made for me out of something that won't ever fail again. They'll need to be about 16" long by 14" wide and 13" tall with a solid bottom and a flip top. Any ideas?
