Not the end of the world, but you do need to fix it…

The threads do go deeper than the orig bolt, but not by too much.. order a couple longer bolts ( you likely won’t find the right thread and length in any hardware store) and be prepared to shorten them to exactly the size you need with a dremel.

If that fails, put a helicoil in…when drilling for the helicoil, put the other bolts in their holes to help align the angle of your drill. The angle there is a little strange.

I have been through this. As a result, I tighten those bolts gently with one hand using a small 1/4 inch drive ratchet. Tight is right, any more and it’s broken…
