Well I got the 4.6 ones by accident a while back. Didnt notice till after I installed them. The tach is slightly different and so are some of the warning lights. Basically I butchered the warning lights on the stock plates and I saw that the ones I want for my car dont even come with the warning lights. SOOOO I need to find some stock plates so I can transfer that peice.
but it would be sweet to design exactly what you want
