20 x 12 will they fit?

You would need to re-hoop the wheels anyway to correct the backspacing for your application, so you might as well narrow them at the same time since you need new inner and outer hoops. Contact the wheel manufacturer or a dealer for them and see what it would cost, probably only about 30% to 40% of what the wheels cost new all said and told in my experience.
