A stud socket?  These studs are a bit different than the ones on the cylinder heads.  It's just two flat sides instead of the star shape so I'm not sure a regular stud socket will work.  It's worth a try.  That nut is completely rounded off I don't think turning it is an option anymore haha.
HF has extractor sockets but they aren't deep well so I don't think they'll work anyway.  Going to run to town tonight as. I need a long 1/2 breaker bar to get the engine mounts knocked loose through the wheel wells.  My wobble sockets arenet deep enough and a wobble extension on an 18mm deep socket is too high.  When I go grab that I'll get a stud socket and some metal sawzall blades one way or another it's coming off there.  I'll try to fix the manifold later with a new stud or I'll replace it I guess.
In better news, the creeper works great!  And I'm glad I picked up this flexible ratchet because I don't think I'd have gotten that top starter bolt without it.  I've been wrenching for the last 15 years with only a 123 piece Stanley socket and ratchet kit.  It's been great but I needed some better gear eventually anyway.  Nows the time!
