Wanted 2 seat rear bench

[Jason66]

I’m after a 2 seat rear bench to use with the side bed extender. I have the bed extender and it’s to go into a T5 caravelle with the floor rail system. Essentially the Beach two bench setup. Will pay good money. I’m trying to find an easy way to transport an MX bike without having to remove the seats. I’ve cut down a 3 seat bench to a two, with a plan to slide the bed extender in and out and slot the bike down the side. Bed extender doesn’t fit. Seats too wide. Beach two seat bench needed. Saga. I still want to drop the seats to have a full width bed when needed. Any aftermarket ideas gratefully accepted!!
