Bulldog wish i could help ya on the seats that was actually one of my favorite things about my 260. Shouldnt be to hard to build a set though. When i had my vinyl done i got a good look at the structure and its all plywood. If someone on here can come up with some patterns it looks like a good winter project
I was running three blade 23" Mirage props and seeing sixty right on the dot at just under 5000rpm. My 260's were just hoped up a bit to maybe 300hp. Cruised at fifty all day long at right about four grand.
