Kayaken; The Norman pin has standard threads. Each end screws into a piece of threaded rod in the middle so there's three pieces altogether. I had to use a pair of vice grips on each end at the same time to hold it from spinning. And I think I used some folded up cardboard to protect the ends from the vice grips claws so as not to gouge it. I think I still did a tiny bit but luckily was able to file the scratches out. You might need to soak the threads with a little WD-40 or equivelent. Mineral spirits or paint thinner won't harm gelcoat provided the gelcoat is in good condition. If its old and chalky it might soak in and be a problem if you want to paint over it, depending on the type of paint you'd use. I think paint thinner is an oil based product. good luck, Ernesto. 1979 custom sport 15'
