Lost a Darn Banjo Bolt!!! Help! Please!

[regsatx]

OK...Here's the story: Decided to clean out banjo bolts this morning on my 1985 300SD as we finally had a cool one in South Texas...kind of cool anyway. After cleaning the bolt behind the intake, went to the one on the ALDA. My cell phone, which was on my toolbox rang. Engaged in a couple of minutes of needless conversation, went back to my work and my hand knocked the banjo bolt off its perch on the area just above driver side head lamp. It fell...I heard it fall but after two hours of intense search...I CAN NOT FIND IT! Where the heck can it be? This is the banjo bolt with the little fitting on the top for a small vacuum hose to fit onto. Where can I find one...new or used. Oh...I also had both little washers on the bolt too. What an idiot I am. Thanks for any help. Bolt looks just like attached pic
