Hi all, wondering if anyone can help or has had a similar issue. The rear discs on my Astra GTC have failed on its MOT. Unfortunately I'm having a big problem with finding replacements that fit. The disc sizes are all correct however the mounting bolt holes are slightly off by literally mm so I'm unable to fit them. I've tried loads of different disc brands and the same problem persists - can't find any with the correct hole alignment. I'm not a car expert byany means but really am struggling with a solution. Added a couple of images to show the alignment issues. Any help would be greatly appreciated.
