Quick Change Width?

[Dirt Dobber]

I was looking at buying a used quick change for my modified from someone and I was wondering if anyone could tell me what the measurement would be on it for correct track width? I measured from face of hub to face of hub and it was 63". Will that work with 2" off set wheels?

[Confused?]

Most mods that I'm aware of use a 60" rearend.
