I did a search and read all the posts about installing a rear OEM spoiler on an XB.
From what I see, you have to drill 4 holes, 2 on top and 2 on the back of the rear hatch.
the problem is that all of them are blind, meaning you can't reach and put a nut on the other side. So other than the nut inserts which I don't like, does anybody here has actual
experience, actual knowledge about installing one of these?
Please don't write more stories about how a friend of some friend did it.
Thanks a bunch.

 

I installed mine a couple weeks ago. I wish there was some secret that makes it really simple but I dont' think there is, pretty much just line up the bolts, & drill. When you're drilling from the inside, I think a stepping drill bit makes the job much easier, but still takes a while to do, drilling through 2 layers of metal in there.

Good Luck!
