You'll rarely find Curtis wrong on something....but then again the same could be said for Moppie. It sounds like Curtis is typing from experience with this particular car, I was typing based on general knowledge. I rewatched the beginning of the video and don't see a clutch master cylinder, so it would appear you have a manual clutch and the linkage may be for the clutch rather than shift linkage. I assumed an automatic transaxle.
