spoiler questions

i wanted to put my spoiler back on to utilize the led function
the thing is, the sticky part that goes in between the bolts
and spoiler is gone. where would i get those pieces from?
i didnt see a part number for those.

also, if it rains, would it leak alot if i didnt have that protective
seals that goes in between? thanks

go to a hardware store and get some rubber layouts and make a fitment for it, if not then silcone it.

Use rubber gasket material from autozone.
