Switching from 3.08 to 2.73
Right now I want to get better highway mileage I currently get just under 23 mpg. I wanted to know if anyone had any suggestions, thoughts, concerns about putting a 2.73 gear set in place of my stock 3.08. I am also planning on replacing the stock differential with a LSD differential out of a 01 Mustang. I have looked for the 2.73 gear sets and all I can seem to find are pinion gears with 30 splines and the stock splines are 28, so I would have to get a new pinion yoke to accept the 30 splines.
Pleease let me know if you have anything to offer up.
