On the 28/29, the package tray can be shortened about an inch to move the seat back a bit. The 30/31 types may not have that option. Other ways are removing the seat springs and building new cushions from foam pads on wood backings to bring the rear cushion back and/or shortening the bottom cushion. There aren't a lot of other options in this respect but this is a common way of making due.
