Thanks for the info!
Yes, this time I tried some different bolts. I bought these at ACE hardware. They are the same thread as the old or stock bolts. But the head is a little bigger.
This time I used lock washers before the nuts. I tried to fined some locking nuts, but could not find them in the size that I needed. If this doesn't work I will try two nuts and some loctite.
