Thanks for this thread guys, esp the pics! Did this over the weekend with 17s. Love the way it looks. I have an ARB bumper on the front, and the weight makes the front fenders sit a little closer than the pics I see with stock bumpers. So, I might consider a lift.
For the spare, I ended up raising the third brake light by an inch so it could clear the new spare. Ace Hardware sells chrome one inch spacers, and just replaced the stock bolts with some stainless ones that were an inch longer, which I also purchased at Ace. I believe Warrior Products sells a spacer kit, and I saw a thread where someone made spacers out of PVC. But I didn't have the time to wait for shipping nor the patience to cut and paint some PVC. Any of these three are good options.
(As much as this might sound like an Ace harward ad...I do not work at Ace.)
