Has anyone installed the OEM rear spoiler on an xB? I recently bought one from the dealership and figured that I would save the $100 they charge and install it myself and use the money saved for some other mod for my box. It came with instructions and they are very straight forward but I am having trouble finding the drill bits to drill the holes. The instructions call for 3mm pilot holes to be drilled and then the two on top need to be drilled to 14mm and the two on the rear face needt to be drilled to 12mm. I can't find anywhere to buy metric drill bits. The closest i can find is 15/32 for the 12mm holes which is just a shade smaller than 12mm and 9/16 which is just a shade larger than 14mm.

I was curious if anyone else has installed the OEM spoiler themselves and if so what size drill bits did they use. Any input would be greatly appreciated.

 

Well I installed it last night. I ended up using a 15/32 drill bit for the 12mm holes and a 9/16 one for the 14mm holes. Just followed the instructions step by step and it was perfect. I am glad i didn't pay the dealer $100 for about 15 minutes of work.
