Ha ok that's what I was afraid of----I better go to Harbor Freight and see if I can find an oddball long-armed clamp of some sort to bend that darn tab back into position. The unit still works with a vacuum gun on my '72 GMC and it doesn't need it due to headers but even though I have owned that truck since 1979 someone had drilled a bunch of holes in the filter can part before we bought it. I'm hoping to keep the '70 air cleaner assembly on the '70. I want that valve to work though!
