I'm going to pick up an entire rear with 3.73's to replace my stock gearing in my 92. What entails the whole swap? I'm not pulling gears out but looking to swap the new rear in

Is this from another fox body? SN95?

if is is from another fox body, change the fluid, add friction modifier. While you are at it. inspect the axle bearings and i would replace the axle seals, and inspect the brakes and wheel cylinders,.

If it is from a sn95 with disc brakes, then you will need the rear brake lines for that year, connectors for metric to standard brake line fittings, the E brake able and mount for the SN 95, an adjustable proportioning valve, an SN 95 master cylinder, and alter the E brake handle mechanism. I may have missed a few things. The tires will be moved out about 3/4" on each side,

It's only an inch or two. What's the big deal?
