hey, compared to the r1 hole config as show below
1---2 2---1
3---4 4---3

1-4 being one side of the spoiler, which of the 1-4 holes does the 99 spoler use? and which hole(s) need to patched up because the 99 spoiler doesnt cover it? thnx.

 

well on your hole config there holes #2 on each side need to be covered. i am getting mine on in a week or so. here is a link to see it all.
