Simpson beat me to it, but Im sure 50/50 Acetone and ATF is the go to, then working what movement you can day by day. Rather than trying to force it

I would recommend he re-taps all the hubs, plenty of cutting fluid as you go and a new set of wheel bolts. More often than not with the wheel bolts you'll ruin the bolts before the hubs 99% of time at work fixing said issues from similar stories will fix, and torque to spec

GAZ Shocks in the UK used to do custom ones if I remember correctly, and there was a agent in Auckland I want to say Zep used them?

I've even got a complete long block, manifold, Carb & dizzy you can borrow to mock up

Intech + Holley & XF dizzy???!

Top work on the project, really quite enjoy your updates. I was reading about the Atlantic just the other day and then thinking about this!

I think from memory, Windom, Camry and the weird import Avalon. If I remember the larger capacity is in the Highlanders of same period and maybe Prado? I always thought the 2mzfe was a pretty cool motor 15 years ago, but newer stuff surpasses it now

If you get stuck I have a muncie rebuild how to with from memory a section on the Hurst Shifter. (in saying that on youtube there is lots of videos) But basically I would polish up the plates and lightly grease. Have the linkage bushings tight (or if you really want to splurge get spherical rod ends) , and once you know the throw from the lever itself, the hurst housing should have some threaded holes - for a nut/bolt to be wound in as stops - that way you can smash gears as hard as you like against the stops without over throwing the selectors
