I have no springs for the adjuster lever or the front back tensioned movement of the seat.

Evidently the seats for the Jetfire are different than the convertible seats. The two Jetfires here have a lever adjuster up the side of the seat with a “rotary” spring to tension of the adjusting lever while the two converts have the lever coming out the front with what I think is a standard type coil spring with two hook ends under the seat on the frame.

Perhaps other hard tops have the same seats as the jetfire, don’t know.

Does anyone know where I can get a set of springs or give me a dimension of the springs so I can pick up some close ones at the hardware store. Lots available on line but of course not for this application. Maybe some knows what application will fit these seats?

Converts only have the drivers seat adjustable, passenger is fixed.
