Need Help With My Dipstick Tube, LOL

[MotoRider42HC]

OK, so, this might be an extremely stupid question, but i'm having trouble finding the correct dipstick tube, or maybe i am missing a bracket somewhere?

I bought a dipstick tube for a 2007 Chevy Silverado 1500 2WD, which is supposed to be the same engine as I have in my shop.

BUT.

I could not figure out how to mount the dipstick tube. The mounting "arm" just would not line up to anything at all.

If anyone has a part number for the correct (Camaro-style?) dipstick tube???

Or pictures of your dipstick tube???
