Need help with tracking down correct bolt sizes...plz!

[Happy Hummer]

After much swearin and hours under the hood of GF's 2week old H3 ('06 84k) found some disheartning things.
1) TB filthy
2) TBS incorrectly installed by po...
3) The bolts holdind down resonator intake were stripped and narled.
4) took hours to get it all apart and many trips to hardware store to come up with temp hold down.

Can not figure out where to look for these hardware items. They are special size. Mcmaster Car didnt even seem to carry this very item.

I think those are called Tinnerman nuts. You can find them at racks at some auto parts stores or auto body and paint stores.

Mr Rich is correct. You should be able to find them at hardware stores also.

And in the auto industry, we call them U-nuts...

If all else fails, replace that resonator with an AirDoc!
