Trying to replace the rear shocks on my CX-5, but the lower shock mount ring has become seized to the mounting stud. I actually cut the shock ring off with a grinding tool then spun the stud out with a plumbing wrench. What a nightmare. The old stud is toast - curious if anyone has replaced the stud with a bolt. If so, anyone know the size or a part number that would work? I cannot even find a replacement stud part number online or the specs for the stud. All of the parts stores seems to show a bolt, which my car does not have. And i am not sure if i order this bolt if it would actually fit. That part number happens to be 9YA0-21-450.

Any input would be greatly appreciated!

thanks,
