Can you identify this part?
 

Hello all. My uncle has a 1980 V6 Camaro. He lives abroad and it is very difficult to find parts. I have am trying to find this part for him. They told him it's the "vacuum valve" and also told him EFE-TVS and EGR-TVS but the parts I found online at rickscamaros, classic industries and even auto zone don't match the picture. Can any of you identify this part and tell me what I should order? I would be extremely grateful!

Try checking out Rockauto.com since they have a bunch of different pics from different vendors. Though not exactly the same the one on the right looks like the vacuum control valve when I was looking on rock auto.
