i member when we were younger n dad was a subcontractor he couldnt get a dual cab as a work vehicle so he bought cant member what type but had a space cab with 2 seats in back n with having 3 daughters he himself put a 3rd in, he just mounted the middle seatbelt to the seat belt anchor bolts of the other 2 (piggy backed) and made up a seat to basically custom fit between just with some boarding, foam, n material over the top n staple gun it together to underside of board... hides any join n can get material same or similar to ones already installed..... then u can either bolt the seat part down or like dad did if its cut out to perfectly sit in gap it wont slide.....hope that helps.....
