After digging out my Frabill for the ice fishing season, I decided I wasn’t truly happy with the bench seat. Not having the $$$ to buy the new modular seated model(they are really nice), I started shopping for a new seating system.
I came across some nice fold down seats at Wal-Mart for $20. The swivel assembly that attached to the bottom of the seat fit perfectly across the framework under the old bench seat. After taking some measurements, I drilled 4 holes and screwed the swivel to the frame. Then it was a simple matter of screwing the seat to the swivel and adding some aluminum can holders to the frame for added convenience.
