Exhaust Crossover Bolts

While changing the thermostat on my 99 Venture this weekend I suddenly acquired the strength of the Hulk and snapped one of the three bolts on the exhaust crossover flange, front of the engine. It was after the parts stores were closed :runaround: so kept going and put everything else back together. Do I need to worry about this? I do intend on getting back to the crossover and changing all six of the bolts (three on the front flange and three on the back one) but I'm out of time before my family holiday trip, about 800 miles all together.

I'm an engineer by trade so I'm not comfortable with 2 out of 3 bolts :nono: but I'm also figuring that any exhaust leak would be minimal. Would there be any cracking or other failure involved with these joints if left for too long?

it could leak, start it up and find out...only way to know for sure. if does leak but not pointed at any major parts(i.e. plastic and so on) then should be ok, but would fix asap...as i am not a fan of the theory that if 2 bolts won't hold it, 3 won't either
