New Replacement Blue Back Housing Plate for iPod Classics 6/7th Generation. No GB on the back of this one. These are OEM quality and fit great. Many repair places like a new backplate to meet the capacity of the iPods. This fits that perfectly! We do have other classic parts and sizes, so see our other items. Including matching color faceplate/center buttons! Please note, these plates do have random serial numbers as well, they aren't just blank. Thank you!
