Oops I meant #4. I will check my stash of bolts for a 8x1.25 30mm bolt tomarrow. I did replace the #1 bolts with a bit longer bolt and it fixed the job when I
had basically the same issue last year. I think the bolt is short and the 1st little bit is lacking thread. Heat cycles could be a factor thats why I asked about
lock tite of some sort to hold it from moving. the complete system has no stress ( as long as you dont count me). Everything is in tip top shape with no rust,
Clean and all brackets are there and doing there job.
Thanks for your input all. I guess I need to put it on the lift and fix it this week. Thanks
