Got the shock mount fixed. I picked up a 12mm - 1.75 x 30mm bolt from my local Ace, cut the head off, tapered the end of it, cleaned the area, and welded it the best I could with the room I had. If I took the bed off, I could have gotten the top better. After these pictures, I dressed it with a grinder and dremel. I got the shock on and the nut tight, so I am happy.
