I had the same problem, got knocked back 2 days before rego was due, all i did was ordered the tie rod ends (had to pay upfront), then showed the rego inspector the invoice, and he was kind enough to pass it (as long as u get them put on he said),Like i'm gonna buy 2 new tie rod ends then not put em on
I'd talk to the guy an see if he'll do the same, you might be lucky.
They did take about 2 weeks from japan, and i'm not aware of any other replacements.
Got them put on yesterday along with a wheel alignment, and the steering is feeling much better, seems tighter and more direct.
Beastien.
