My son just bought a 1977 glastron T-166xl boat,, he got a great deal We think,, $500, it has an 80 Hp Mercury moter,,thats needs a tune up, trailer has new tires,, working lights. The fiberglass is in really great shape,, it needs some cushions replaced,, the top has broken arms that are held together with tape.. Where can we get replacement parts? would it be better to get the cushions reupholstered? We are exctied to help him out with this project and get it in the water soon for a test drive..
