I haven't calculated the cost yet. The Saturn SE is 64'' WS. and should weight around 8.5lb . I have a set of plan that i can get copied, I am not sure if there ever was a construction article on the Saturn. If everything pans out i could also supply the cores if needed.
This plug has not been used in over 30 odd years. It does need some tlc. to bring it back to par.
Will keep you posted on the progess.
