Looking for wheels

Just an update if anyone is following. I mocked up a wheel today using cardboard. I made it 15x11 to make up for the lip on the wheel. I made it with 5" from the inner edge to the mounting surface simulating about 4-1/2 backspace. If I moved it in another 1/2" on the backspace it would fit but would be very tight and that's with no tire sidewall. So I don't think I'll go that route at this point. Looks like it's gonna be a 15x8 wheel or the minitub and spring relocation. I really want the meats under the back and don't want to compromise or skimp out on it, so most likely will be doing the mods. Thanks to all for the help.
