It's your call. If you want a factory stock look go with the "funky" fender and the stock spare tire carrier.
If you are ok with a non-stock look mount the spare on a custom mount between the fender and the cab.
It's all good... pick a theme and run with it.
Note that there are different fenders for a short bed with a spare and a long bed with a spare. Check out post #11 of my build thread here:
