Fitting bench seats in a 3Door LWB !

I'm looking into fitting bench seats in my fender I bought recently. I think it may be a bit unusual ( any comments?) Its a long wheel base with three doors, windows and just two front seats?

Any how I want to fit some inward facing bench seats. Does any one know the best way to fit as many possible. I think a 3 man either side would leave a space both ends of the wheel box. That space originally being used for the 2nd row of seats in the station wagon.

How many could I fit, and what combination. Two two man benches either side, or one three man and one two man either side? In need of some knowledge!!

All 3 door defenders & 110's come without seats or have easily removable bench seats in the rear. Usually have 3 seats in front but most people bin the centre seat and fit a cubby box in it's place. Best bet is too measure the interior of the rear and then measure the seats to see what will fit.
