Find a 90-92 rear with better rear brakes , limited slip and 3:23 or 3:42 ratio. These are 10-bolts with 28 spline axle shafts.

You will need a 26 spline Eaton posi. an installation kit and a set of gears. There are no 3.55 gears for this rear end. Your other option would be a 3.42. Send me an email or PM if you want prices on the parts.

I would think that if you have a lot highway driving then you would want the the 3.42's. You'll probably get crappy gas mileage with either set of gears but better with the 3.42. It all depends what you are looking for.
