New pedestal and seat question

[TimPierce]

I have a 99 Lowe 170 with 1.77" bases. I just bought an adjustable stand up pedestal and a butt seat for the front. The pedestal has the standard 4 hole configuration on the swivel plate. There is no hardware on the bottom of the seat. Question is, is there a particular piece of hardware or screw/bolt size for properly (and securely) fixing the seat to the swivel plate?

Never mind. This was a stupid question. My seat had screws already in the bottom for installation that I didn't notice before. The weather has frozen my brain! My apologies for the waste of web space.
