Exhaust Studs??

I had mentioned to a few that my exhaust nuts on the 66 had worked loose and that one was completly missing, causing the exhaust to rattle a bit, well I finally got the nut to replace and discovered its a 9/16 vs the other 3 being 11/16, thought it was strange that the stud was different on just one, after crawling under car it looks like the 9/16 was on there cause the stud was worn down, cant seem to get it all the way on again and it looks like the exhaust manifold gasket/dounut is worn out : (

It looks like getting the stud off to replace would be a B*tch, has anyone done that b4 and can comment? am i better off taking it to an exhaust shop and have them do on lift?

Are you going to replace the exhaust gaskets?

^^ need to replace donut/gasket between manifold and pipes

That shouldn't be too bad
When are you doing it?
Need a hand or beer?

Not sure, I guess I can try it, if not, any AA County peeps know of a local shop for a small exhaust job??

well got under her today, replaced the dounut gasket but no luck with the stud, wouldnt break loose and its rusted/stripped so I cant get a bolt on it.

The guy at Autozone mentioned i would need stud remaoval tool but if it that old may be rusted enough were you would need to heat it up some, called MD Muffler and they said it could be a pain to get those off being that old, couldnt give a figure except to qoute their hourly rate : ( he said it all depends may need to drill them out etc.............

I plan on seeing how the one bolt holds up, if it will maintain it snug enough or loosen quickly, let me know if anyone has suggestions........
