those are alternative impact wheels right??? had the same kit on my old rev... wanted them inside so i just cut my axel and tapped one side for the two wheel kit... DONT DO IT.. with the relocation brackets it looks way tacky, doesnt do justice for the size of the wheels, they look like 8's because the bracket hides most all of it... leave them on the outside they look way better and you wont notice much of a difference relocating them.. my 2 cents otherwise do like i did and make it out of your axel you already have.. if you cant do that take it to a machine shop, they could pry do it for half an hour of work.. pry 20 to 40 bucks..
