Trouble Selecting Gears (linkage bushes??)

[MR2 Livvy]

This may be a little long winded but bear with me!

1993 Mk2 Rev2 SW20 e153 transmission (as the amercians call it)

2 weeks ago I couldn't get reverse, I could only access 1st 2nd 3rd 4th and 5th with a bit of effort. So we replaced the selector cable bushes with ball bearings...easy win!! all gears back

Friday can only get 3rd and 4th all other gears will not select. I can move the knob in the cabin into the positions for gears but it only ever selects 3 or 4th (up or down essentially)

So i'm thinking the square brass bush thing?? shown here https://www.youtube.com/watch?v=T65f5YxG4ak

My questions
1. Whats this part called (about 1.5cm squared brass bush)
2. Am I barking up the right tree

I've read you can rotate it 90deg to get the unworn sides, but if I have to do that I may as well replace with new.

Any help appreciated

Think the brass bush thing might be phosphor bronze. Turn it around and try perhaps?
