Trying to figure out what I have.

[Dunn51]

Hey guys, so I recently picked up this new to me vessel. The registration from the previous owner says it’s a 74. I’m just trying to get this thing back to be a solid boat. Nothing super fancy. It will be fished hard, I just want it to be sturdy and reliable. I have a few pictures of what I’m working with. Any help would be appreciated. I’m trying to figure out if the cap is supposed to be glassed in or lay over like it was when I got it.
