I reached out to a few members about the gear selector mech pins/springs and no one ended up putting a kit together.
So I just bought them from he Aussie site. Parts listed at $28 AUS, so it became $18 USD

BUT the shipping was another $20
120 Prado / GX 470 auto shift lever repair kit

I also ordered the bushing insert as preventative. I havnt touched/messed with mine, but figured better to just do it while im in there vs it breaking and not being able to get into gear or park while out somewhere..
Few reviews said they used it on their 470 and worked great, and it was on sale for $18 vs $29
