Default Vacuum motor behind speedometer question

Alright, this is frustrating.. I'm about to pull the dash to check vacuum lines, clean up, and I'm wanting to replace the vacuum motor behind the speedo. I cant find the part number anywhere. Found YH1538, but no pictures can tell me if this is the right part or not. Anyone replace this before?
