Seat pedestals?

[Illgotoo]

I'm installing a new wooden floor and seats on a 16' Eaglecraft tiller. There are existing pedestal bases, but missing pedestals and seats. The bases look to accept a 2" pedestal. Where can I find a 2" pedestal to fit what's there?

I can install new bases if necessary, but I'd really like to use what I have if I can.

Here's what they look like...

This just in. I think there is another piece, a male spigot obtained from the boat manufacturer, Daigle, that mates with the existing female spigot. The male spigot has hole patterns to accept a standard base.

That sound right?
