I was just replacing my air cleaner mount with a new one. I was able to remove the 3rd (hard to reach) bolt, but when I went to put in the new mount, I dropped the bolt!

I couldn't find it, so I came online to ask if I could just buy a new one and hope the old one is not going to interfere, but if it fell into the turbo that's something that needs to be removed. I can't even see the bolt. Can anyone suggest where it may have fallen - I thought the turbo was horizontal, so I don't see how it may have fallen in there...
Thank you.
