Ls1 or ls2 into 88 shortwide stepside.

There is two ways (well, theres more, but two main ways) to know how narrow to make a rear end. The first is to get your wheels and tires, stick them in the wheel wells where you want them to go, and measure between mounting surfaces. Otherwise, you use a whatever rear end you have and calculate the offset on the wheels. So I guess theres only one that requires a rear end narrowing.....

The point if narrowing is to put more meat undeneath, I can tub or whatever.

And until you have your wheels and tires, and mock them up, you dont know how wide to make your rear end........

that's a nice looking backhalf, & at a fraction of the cost to have one custom made.
