I've found every one except the classic gaming gear, and the gold dragon claw statue with clockwerks message at the bottom. I really want to find them to unlock the arcade, i can help you a bit ones on a boat near the safe house. Near that pink dancing chicks house mrs. Gaiza? theres those crates with the monkey parachute over it. There are like 4 crates and 2 of them have treasures on them. If you've found those i apologize those are all the ones i remember.
