none...i personally would just assume you built the car anyway...if you didnt itd be obvious....actually ford built it and they already have emblems on it....
I have one sticker across the top of the windshield for the race shop the car was taken too by the previous owner. It looks good and I get a discount on labor if I take it there for anything so I left it. The only others are the stock emblems/stickers on the side quarters.
the only other stickers/decals on mine are a ziebart (p.o.) and a small summit on the lower corners of the the back glass. all my other parts stickers i get go on my toolbox at work.
