I have a good working set of trim tabs from Boat Leveling Co. St Louis, MO (exactly what it says). I'm looking to bit a trim tab indicator on because I dry store the boat in the summer and that fork lift will take them right off if they aren't up all the way. Are these guys still around? Or is there anyone who makes parts for this system? I hate to replace a perfectly good working system just because I can't get parts for it.
