71 Duster rear wheel and tire combination help

I just wanted to thank everyone for the help. Duster2 saw my post and sent me a message, he happened to have 2 15''x8'' wheels and beauty rings, with brand new 275/60 tires on them, that was an exact match to my front. I met him at the Indy swap meet, and loaded them up.

Everyone's recommendation was right, the wheels and tires bolted right on with no rubbing, I didn't need a spacer or anything. Its amazing how much difference some meat in the back can make!!! Here's a couple pics, I'll post some better ones when it warms up!
