Ok need som info.. I have a 1990 220 Overnighter and it did not come with any of the bimini tops.(mounts are there). So my question is what was the factory heights of the frames ? also someone did some wood replacement to the back of the wraparound rear seat and the sundeck/engine cover rubs on the seat back when closing.so if anyone has one they could take some picks of the back of the rear seat from the engine compartment i would greatly appreciate it..
