Exhaust pipe to header flange bolts

[CFreed11]

Anybody know off hand what size these bolts are? I'm looking for the 2 bolts for the flange that connects the end of the header to the exhaust pipes. For a 2002 Firebird, 3.8

thanks

Re: Exhaust pipe to header flange bolts

did yours break?

my bolts were so badly rusted that i had to drill them out, i just got some bolts from the hardware store and put a nut on the end.

im sorry this probably didnt help you in any way, but it was just a suggestion

It actually looks like they just fell out.. The threads look to be still intact on the flange and both bolts on the drivers side are completely missing. The passenger side is fine, but it does appear that those bolts have been replaced at one time or another... perhaps who ever did this didn't tighten them enough or something? I've only had the car since the end of October and this happened literally the last day I drove it before putting it up for the winter. I got the car out today for the first time all winter and this is first on my list to take care of..

Thanks

I can't remember the length but the thread is a metric 10.

thanks guys, i ended up finding a couple bolts in the garage that fit, but me being impatient twisted one of the bolts in half, with the end of the bolt still threaded this time. Well the one bolt is holding it enough for now and some stainless wire on the twisted off side will be my temporary fix until I fab up my own custom exhaust later this summer.

thanks for the quick responces!
