I just got mine the other day. I installed the left one but the screws seem too long by about 3/4" for the two on the right. Not sure what you mean about the instructions not being the clearest, my kit came with no instructions. There was a bag of screws with two spacers (used on the left pop bumper) and two of the screws had nuts on them. I have no idea where those go. I am not sure I am crazy about the mod either but I really hate the el' cheapo leds sticking out. How much do you really save not putting on a pop bumpber cap Stern?

Thanks Marc, didn't see the instructions. I didn't realize you re-use the existing cover from the two right hand plastics.

I saw DEVO last year and they were fantastic. I think that reference has changed my mind. I like it better now!
