My suggestion would be to order them for a TJ Rubicon if you are running larger tires. They are .75 inch wider than stock. Also the stock Rubicon flares are made from a different material that doesn't turn grey like the TJ ones.
I went with MCE 4.5"s flat fenders. (Modern Classic Enterprises)
But my stock fenders were starting to rust, so it was no problem for me to cut the front ones up. My factory Sahara flares themselves I actually sold off for a few bucks.
