Todd,

Step back for a second. Those bolts are suppose to be SS 304 or preferrablly 316. The real question is did you strip the threads. Then you need to retap and upsize the bolts or use a helo coil repair. Retap is simplier. Those bolts are threaded into an aluminium backing plate in the glass. If this is damaged or you want to increase comfort you may want to add a lock nut to the rear strap bolts. An additional through bolt into the inside of the tube like the front crossbeam may give some comfort.



Good luck.
