Yes, due to the angle and space restrictions, I anticipate a great deal of difficulty if not impossibility of trying to drill straight holes into the bolts. I think those plastic things would do the job. Do you know what size holes I would need to drill to fit those in?

Trav's suggestion is great, but exactly locating the bolt center and drilling perfectly plumb with a hand drill in an awkward position (no lift, I assume) is probably a cake walk for him, but more difficult for us weekend warriors.
Consider alternatives if things go awry. As mentioned, it would be simple to drill two new holes an inch away from the welded in ones, run in a self tapping bolt, and be done with it.
If your drill hole goes bad (off center or crooked), just drill it out over size and again, run in a self tapping screw.
You could probably even use a
high quality plastic push pin type of fastener and forgo any threads/threading.
I'm just preparing you for how things sometimes go and that you can probably get away with not establishing new, high quality machine threads.
Make sure you slather everything in antiseize to slow down future rust issues.
Good luck!!!!!
