hi, i have a set of clips on the port side, inside wall just above the speaker. looking online at other 296's i have seen a seat attached there.when the bench seat is out, the detachable seat gives the bench seat an L shape look.trying to find info on this seat and anybody who has one, maybe don't use it. would even like to find the brackets that clip into the mounted clips and make the seat. any info would be great.
