It could be excessive endfloat in the gears, or it could be a bent selector fork. Or a sheared off roll pin on that gearset.
Micheal Van something is a gearbox guy down your way. If you get stuck hit him up.

broken syncro fork

Easy fix then.
Providing whatever caused the selector fork to break isn't still an issue.
I know of two of two 71b boxes (in bits) that got dumped just recently. (I was too slow to save them)

Yea I'm hoping someone has just abused it over the years and its been cracked and it broke.
Are fj internals the same

I'm not sure tbh.

If those were RBLUVRs ones ive got them at home - there is a 4 and 5 speed

That would be a good place to start for forks.
