I got them to fit. I ended up having to have a bracket made that would extend it out from the tank. I used quarter inch steel (Twice as thick as what the L bracket is that came with the universal seatbelt kit). The seat does fit between them because of the curvature of the bottom back. But it is tight. I’ve since taking it back out again because I’m fixing the mechanism that moves the bench seat on the track. I forgot to take pictures of it with the seat inside.
