I’m sure it is the 3920cc engine guys.
Problem with these I have found is parts don’t seem too easy to come buy, not the little parts like bushes anyway.
I did read it’s more likely sloppy shift gear than the linkage but I haven’t looked yet…
That rod in the picture, should it be solid or should it have enough play side to side… and is there a bridge repair anybody has found successful for the shift stick slop
