Well this weekend I purchased my girls (16 & 14.5) a 1998 Cavalier Z24 and it had an exhaust leak. Looked to be the gasket between the Manifold and the down pipe. Picked that up and when I got into it I found that one of the bolts that connect the manifold to the down pipe is broken off.

The previous owner (some relatives) did state that it had been slid off the road into some deep snow and the exhaust was worked on after that. My guess is that this happened at that time and now I'm trying to get it fixed.

Well I can not get the other 3 bolts on that flange loose from up top so I removed the manifold nuts from the head and am planning to remove the manifold and down pipe as one piece to the converter. That way I can work on getting the other three bolts out on the bench.

My question, what size are these bolts and where can I source them? Autozone does can not get them and I don't see them on GMpartsdirect.com and I really don't want to pay dealer prices on some bolts.

Any help is appreciated.

TLC / Maintenance being done before put on the road:
1) Plugs & Wires
2) Battery
3) Air filter
4) Coolant Flush
5) Brake pads and rotors
6) Fuel filter
7) Oil Change
8) Brake Fluid Flush
9) Throttle Body Cleaning
10) New Tires

Anything I missed?

 

Well stopped at dealer and they gave me the size, M10 x 1.5 x 35.

Still trying to get the damn thing apart.

This exhaust is going not be much fun.
