I have a 2001 Chevy Malibu LS. I was hearing noises from my exhaust system (I could hear the puttering of the engine), and took a peek under car and saw that it looked like my exhaust gasket needed to be replaced (between the resonator and muffler). I took a wrench to loosen the nut, and it turns out the stud/nut was completely corroded, and snapped off with the lightest turn of a wrench (which is why the exhaust gasket was making noise, since the stud was shot). I looked to see what stud to use, and found on one parts site what they proposed to use an M10 x 1.5 stud set. The original stud was M8 it appears (it is a 13mm nut, so that means it was an MCool. The new studs are 62mm long, which seems too long (I haven't taken the whole thing apart yet, so I can't tell yet). I have no problem tapping it, and putting an M10 in will be better since the M8 is all rusted, but I'm think the new stud is way too long, and can't find any specifications for it. Does anyone have the specs for them? Or should I just drill through and put in a stainless bolt/nut? Thanks for any advice!
