I don't think it is really monster online part fault. He (Patrick) work this company call GM for get clamps. GM keep ask him what size. I told him I dunno because I ordered it from gm part #. He told me that he didn't pack it. He order it from GM then send to me. That's why it is mess up.

About weld thing... I think I better do clamps first to let exhaust to see if they are okay then start weld it. What if one of part failure but they are already weld. I'm kind stuck if I can't remove if they are already weld?

Jason M.: since you know I'm working night shift. I don't have gm part # with me but it is on page 2-3 for this thread about part #.
