Where to find some of this stuff?

[GillV20]

I know Craigslist, but where else is there a good place to pick up parts?
What I need is the rear hatch cover on the Starboard side.
The two hatches on the floor.
I am guessing I need to go with hydraulic steering as I am using a 225 to push the boat.
Scuppers for the transom drains.
And I think that should do it for now....
