My 307 came with a exhaust leak, the PO tried to replace a leaking donut gasket from the manifold to the pipe but the bolts broke when removing it, the bolts were able to be removed and threads were good, but he couldn't find a bolt long enough. Where can I buy these bolts?

I don't know what they look like but I have found this...

It pulls up this one for your car.

If you measure the distance of the pipe flange to the manifold flange what do you get?

That's what I found also. I have a plate that goes between the manifold flange and the down pipe, it has a buffetfly valve to close off the exhaust partially on the driver side. Not sure how long of a bolt I am going to need, I might end up having to dig into it without parts to find out how long of a bolt I need. I just prefer having parts ready to go before taking things apart

A muffler shop might have what you need.
