If I was more concerned about fuel milage I would look for a 3 series posi and run my Richmond gear camaro 6 speed
I have not figured out how to make the shifter grab all gears moving it forword enough to keep a bench seat

4l80e 3.73 posi will get fair fuel millage it would be close to my old service van with a 4.8 and 4.10 gears with tire size taken into account

Two young kids need to keep a bench seat
