Was that really necessary?
Wow...guess you must be a materials specialist...you go on ahead and keep on reusing those single use bolts...by the way, the factory installs TTY bolts in a similar method you described...so, once they stretch, they don't snap back.
I'll spend the $45 for at least some factory replacements and be much more confident they're not going to snap when torqued to spec...and yes, I have had it happen.
press on krazy...
