Where to find used boat seats and collar accessories????

[Arizona2ride]

I am looking for some used flip up boat seats under 50 bucks. I have some that are on the boat and in great shape as it is. But they are the kind that have seats behind the drive and passenger and faceing the back of the boat. They fold down to make a bench.

I also have 2 seats up front that have cooler buckets under them. But since the company is no longer in business I cant find the little buckets to fit the cooler spots. They are roughly the size of a regular sink side.

Anyone know where I could find these items?? Jaime
