I have 2002 manifold headers and need new exhaust nuts to bolt the h-pipe to the manifold.

I could not reuse my 98 manifold/h-pipe nuts because they are to big. The 98 manifold studs are wider than the 2002's studs.

I need the exact size of the nuts: Fine or 'wide' thread, thread width, etc...

I'd like to go to a hardware store if possible to get them...I need 4.

Thanks!

Not sure on the size, but a warning with metric threads. There can actually be 3 different thread pitch sizes per bolt shank size.
