Thanks, that's what the last person did, but the Konis couldn't be ground enough.
I figured out how to fix it last night. I used a 5 inch piece of grade 5 7/16 threaded rod, a couple of nuts and several 12mm washers. placing the threaded rod through the shock mount, I put the two nuts and washers inside the mount point and used them to spread the metal. It takes a few minutes, but it will make the hole large enough to install the shock without grinding.
You can also use 3.5 inch or longer tap bolts. I tried using 3/8 inch A307 tap bolts, but they were too soft and bent. I even bent the grade 5 7/16 rod, but it was strong enough to get the job done.
