Here is what I did. I went to the local hardware store and purchased 4 stainless steel bolts. I got ones that were about 1/2 longer than the original. This gives them a little more shoulder length between the head and the thread (right where they break). Tensil strength is about 8 times the strong as the mild steel bolts they come with.
Here is the hard part. The heads on the stainless steel bolts are about .020 to big to fit into the rubber bushing. I happen to have a lathe so I just turned them down to fit. A drill press and a file will work for this.
The "12" update rubber bushings will except the larger stainless steel bolts without modification.
