Steel frame, horizontal dropout bike? If so I'd squeeze the rear dropouts together to match your hub. Afterward you might want to take a big crescent wrench to realign the dropouts so they are parallel.

If it's an aluminum frame or a bike with vertical dropouts, I'd rethink the whole project.

One other thing to check is the number of spoke holes in your hub. It's probably 36 but I wouldn't assume anything.
