Well, I certainly didn't mean to say that ... what I tried to say is that
the vertical link did not change. The trunnions DID change, and became
different from side to side.

Yes, they are unique (AFAIK) to late TR4. As I said, visually they look
nearly identical to the earlier trunnions, the only difference is the 3
degree angle between the pin for the A-arms and the threaded bore for the
vertical link. I believe they were literally the same casting, just
machined slightly differently.
The 4A-6 trunnions look very different (starting with not having a pin at
all but a hole for a bolt).
