Im having trouble deciding which one is the correct size. I found two different size but no correct answer. First size is M8-1.25x25mm. The second M10-1.50x27mm. I drive a 2000 camaro z28. If someone has the right answer please let me know since some of the threads I came across on here were inconclusive. Thanks.

Are you looking for the studs that thread in to the exhaust manifold collector to bolt the catalytic converter up. Or the exhaust manifold to head studs ???

Yes, the studs at the end of the catalytic converter to bolt onto y pipe.

Thank you. I came across these at autozone. Total lenght is 62mm. Part # 03133. Can I use those?

Ya those should work just fine, I don't think the 3mm differance will be noticed.
