Good point Yoda Bill, my bad for not explaining the basics.

I started a thread in the Rig Build and pics and just plain forgot to keep giving all the vital info on this thread. I will check and see if I have a tap and die set, my feeling is that its metric and I know i dont have one of those. I will stop at Auto Zone to see what nuts come with their replacement exhaust manifolds and go from there and check out their Help section.
