Yep, Byron called it, LX Torana. Didn't even think of the LX, I knew LH was the same as HJ. So the change was during LX and after HJ... The July 77 HJ parts catalogue is just listing the late LX surround as it supersedes the HQ/HJ/LH/ early LX shifter surround.

Unless I can find a 76 HJ catalogue that lists the later style.
