Thanks for your help Bob, I will try and work out how to get some pics up on here. The thread is stripped out. When I looked at the bolt it looked like the thread was stripped itself. But then I noticed that the material stuck in the thread unwound off the thread on the bolt. And that the thread on the bolt looked fine. Then when I go to put the bolt back into the frame to do it up. It slides almost the whole way through. Could possibly put a nut on the back if I sourced a new longer bolt and nut...
