So were talking about 1/2 inch in the front bolts and 1/4 inch in the back. That is not too far off since you get to split the difference for each. I think it will fit!
Also thanks for the great spoiler site. I did not know that one existed.
It would be nice to have someone else post pics if they have done it before
flip.
