Thanks guys for your replies....the boat came with no hatch covers...the deck does have a factory "patterned" non skid; don't know if this would determine 69 vs. 70. As for the fuel tank....the boat also came without a fuel tank. Basically i bought it from a guy who was going to restore it, and he bought it from a guy who was going to restore it....so it's missing some items that might have been removed in the past. Once again thanks for the replies...at least i now know that its definitely not a 1979 model as the new paperwork states.
