70 Duster Wheel Backspace w/ Minitub

I've done some research but haven't seen a lot of Dusters running 325/50's on a 15x10" rim. I already have the tires and a 15x10" rim w/ 6.5 b/s that came off a Roadrunner. The tires are not mounted so I can't just try it on. I was hoping somebody on here has used this combo in their minitubbed Duster. Pics would be great!
