I have an 18' 88 SeaRay Bowrider, currently the port side of my back to back lounge seats are deteriorated. I have purchased 2 new std B/B lounge seats w/o the bases, since my bases are glassed & carpeted to the floor. The mfg of the new seats said I can use the existing hardware to mount the new ones. I need some assistance in the removal of the hardware on the existing seats. Can the old seats be removed from the tracks attached on both sides of the seat base? Any help would be greatly appreciated, I am going on vacation next week where my boat is and was hoping to install them while there. Thank you in advance.
