1994 Geo Metro - how important are my frame bolts?

I’ve been told that two frame bolts are missing from under my car but that it’s OK to drive…how concerned should I be?

It is going to be difficult to communicate the location and purpose of these bolts so how about a picture?

It all depends on who said it was not a problem . It seems that a matching bolt that could be removed and taken to a hardware store to find a match that would solve the problem. Or at least have a body shop look at it.
