New Throne for the Captain advise

[willy]

Been waiting for the right one to come along, found it this week, it out of a 31 foot Contender. Will be a real good change from my two too low helm chairs.
Need advise on a couple of things.
-These were installed on the Contender with just screws into the cockpit floor. Is that the norm?

-when i remove my pedestal seats there is going to be six hole I think each, best way to fill and finish so I don't look like a podunk on the water?

-doing bolts where the seats were and where this is going to go, no real access, should I use one of those marine expansion screw set ups. Do they hold up well?

- you see the foot rest on the front, well there are the same exact mounting brackets on the back, any idea what those are for? they are too high for a cooler holder and it came with a strap set up for that.

-cup holders are missing for the holes you see, is that something you can normally buy somewhere?

- I know, I am a pain in the arse!
