Hello all. New to forum. I have looked and looked but have been unable to find any info regarding changing out seats in a boat. I have found many online that I would like to order but unsure of whether or not they will line up/fit on the existing pedestals that are on the boat. This is my first boat so I'm learning as I go. I am looking to replace the 2 captains chairs/seats that are on my Renken center console. How do you know if the holes will line up etc? Any thoughts and ideas are appreciated. Thanks.
