iPhone 5 Color Conversion - Experiences

Hey Guys,

I wanna ask you about your experiences with Color Converting your iPhone 5.

I recently bought a new back housing off eBay and it seemed like the drilling holes for the brackets on the sides are just wrong drilled (less than a millimeter), so my Screen won't quite fit.

Did it occur to you before? Or do you have any solution to this problem?
