Brandon,
I purchased my Midstates in 2003. I have the 15 inch wheels.
My specs are:
Front is 15 x 8 by Ford 4 1/2" bolt with 4 inch backspace. You can go 3 1/2 to 4 inch backspace.
Rear is 15 x 10 by Ford 4 1/2" bolt with 5 inch backspace. You can go 5 to 5 1/2 inch backspace.
I went with the Boyd Smoothies I. They come with those backspacing. No special order.
