The extended box are for sale at Billet racing, they are now called ITS boxes (Integrated Transom System), increased steering handling over 70 MPH and easier shifting in and out of gear higher HP engines, my shift feels like nothing shifting in and out of gear even with the 1.14 gear, two things to remember though, your turning radius will be longer and the trim lift will be lower do to the restriction of the box, nothing you can do about that, it is what it is, you have to give-up something to get something here.

Guy on fb swap shop HSS a nice 3" raised box for 1000

Thanks for info guys
