Default Broken exhaust studs.

Hi everyone,

I am replaceing the 4+3 on my 88 with a tremec. Well I broke a few studs on the exhaust. Does anyone know what size they are and where to get them?

Thanks
Bill.

I'm not sure on an '88 but they'll either be 3/8" NC or 10x1.5 metric. Any real parts store should have them listed by application.

When I broke the studs off during an engine removal,I took the exhaust manifolds to a Meineke and they heated the bad ones out and installed new studs for me real cheap.This meineke was on main street in Peekskill where I lived nearby at the time.

If you can do it yourself then any parts stores should have the replacements.I also did something else,I added stainless steel nuts to the studs and they did not rust for years and was easy to remove again when I needed to.Using basic nuts will rust again and seize up on the studs.

Thanks for the replys. The studs are on the down side flange. God help me if I have to take the exhaust manifolds off. The 10x1.5 sounds correct. Now all I have to do is remove the broken parts.

Thanks guys,
Bill.

I found some in the "HELP" section of the parts store. Also my local NAPA knew right off which ones they were.

That'll work and so will brass nuts.
