I there's been a few smog pump threads recently and I didn't see anyone mention that in the removal/installation process not to lose the spacer that bottom bolt goes through.
You may not even notice it. I wouldn't have if my toyota mechanic friend hadn't told me it was there and not to lose it, mainly during the install, when you push the bolt bolt through it 99% time pushes the spacer out.
Its about the diameter of dime, 1/2" depth with a hole for the bolt and sits in the mounting bracket hole. I imagine you can still install it with out it but it and run it, but it may not be 100% aligned or something.
Just and FYI others can chime.
