Bung plugs for a Sparks mid-pipe?

[eyduc]

I just installed my Sparks mid-pipe.  I need to find some bolts to plug the two holes.   I need  to know the bolt thread sizes.  One on the front pipe is about a 10mm and the O2 hole is an 18mm.  I'm only guessing the 18 is a 1.50 pitch but have no idea of the 10mm.  A normal 10mm x 1.25 pitch doesn't fit.

it's 10x1.  i lost mine and put a home depot stainless bolt in it until i picked up a new one.  used a hacksaw to shorten it.

use copper gasket and thread antisieze.

Thanks for the quick answer.  Was the 18mm a 1.50 pitch?

i am not sure because those sensors are all the same, FWIR.  i am pretty sure they use "Fine" pitch for everything for better sealing which should be 1.5 for the 18mm.

Thanks!  I can't believe how hard that thing is to find.  Even Fastenal is having a hard time.  They might have a long one that needs cutting down to about 15mm.   I want to start that beast now!!!

I want to car craft last week and they went out back and took 2 plugs out of exhaust they had and sold those to me.
