Here is the seat Rickk had made for his 170.Fellow member Randy Duggers is the builder. He is located in Sarasota, but I'm sure he could ship it. He does great work.
I got mine from a builder on eBay, but I can't remember who exactly it was. It was like just over 600 bux and comes with 4 rod holders, a removalble backrest that goes in 2 of the rod holders, a flip up seat with a storage tray, and a foldable foot rest.It was a bit tall for my boat and ended up cutting 2" out of it to lower it down. I messaged the builder to ask him to make it shorter but it was too late and it was already made and wrapped up for shipping.
