The rear bolts in the pictures keep loosening off and falling out. I have replaced with a larger lag bolt and it is now coming out. Unfortunately I can't use a nut and bolt because the underbelly is sealed. Is there a fix for this without having to take off or cut into the protective underbelly material?

Auto parts or big box store "Nylok" self locking nuts. Not impossible to remove but won't loosen either.
I suggest Grade 8 hardware on anything involving those steps.
After the last rivet break, I sucked it up and replaced all the rivets with grade 8 bolts, washers, and lock nuts.
