What rear axles are narrow enough for open-wheel Tbucket size cars? I've heard S-10, early Mustang... How wide are they? I prefer the look of round-back housings (like early Olds, 8 3/4 etc)
Here are some axle widths. Got the info here on the 52-59 Ford group.

First you need to figure out what wheels you plan to run. Ford patterns will narow that chart down quick. Many use the 66-77 Ford Bronco at about 58"
You can also look under www,quickperformance.com under specifications,also have a list of donor axles with measurements for overall length and some from backing plate to backing plate.
