im in the process of restoring my sea ray back to back seats. im making new boxes for the seats to sit on, so i rmoved the old rotted ones and i plan to copy them. i have a 1992 sea ray 220 bowrider. now my question is why are the driver side back-to-back seats different than the other. i mean the seats are the same but the boxes are different, the mechanism that lounges them are different, one is lower. and to me it looks like they are both orignal.
