It seems there probably is a difference. I climbed under my car this evening and measured my driveshaft which had been paired with a TH350. 48.5”. Seems maybe auto cars did have a particular length and manual had another. Now the question is whether or not that half inch makes that big of a difference. My yolk is about a half inch stuck out from the edge of the tail shaft. I set up some Jack stands and my phones video camera and let the axle hang and lifted the car by the rear axle. I only saw minimal travel on the yolk. Even if I were to hit a dip in the road that caused the suspension to fully compress I believe that would pull the axle away from the transmission by design of the leaf springs so I’m thinking I’m ok?
