7 1/2 axle swap help.

Furd Exploder 8.8 will get you a super strong axle with 31 spline axles and 4 1/2" disk brakes for well under $400. They come with tough limited slip, ratios from 3.31 to 4.1. There are a few stickys about doing it. For 1/3 the price of a drum brake 8 3/4 sure grip, you get the same strength and disks.
