the hardware for the front spoiler is cheap also, 3 rods...the middle you got to either drill hole in the frame under or tap for a bolt (I did) the other attaches at bolt holes at the end of the valance...and the rest under the valance with its bolts...
So, you can buy Jims ($10 is a deal) the new at Classics are about $30, if my memory serves me...the attaching hardware is about $15 I think...
and for Catch22, the 400 emblem needs removed ,yes , but I added mine to the rear spoiler instead...(just beware of the reinforcements on the spoiler, dont drill too close to it for the emblem holes, problem with nut for the emblem then , dont ask how I know!)
