I'm looking for the mounting bolt for my 2016 Mazda 6's rear shock absorber. When I look online it gives my a specific part but the part appears to be incorrect, when I watch videos it seems to show this part: 9YA9-01-410 but all of my research is giving my this part: 9YA0-21-450 which appears to be incorrect. I have a mechanic friend that told me I need to order the right part (the longer, double threaded rod) but all of the sites tell me that this part isn't compatible.
