Radius Arm Fasteners (1 Viewer)

[Warra Lux]

Hi All

I am looking to replace the bushings in my father's 80 series front and rear radius arms. The thought occurred to me that the bolts and nuts should probably be replaced as well. However the exploded parts diagram on Amayama shows two types of bolts and nuts(parts no listed below). Is this correct?

90119-16003 - Bolt
90105-18006 - Bolt
90170-18007 - Nut
90179-16015 - Nut

Any help is much appreciated.
Thanks

The front axle mounts are 22mm.
The front frame mounts and rear lower control arms are 24mm.

Not sure if the AUS market cars are different but for a USDM LX450 I used the following:

Radius arm rear nut x2	90170-18007
Radius arm rear washer x2	90201-19011
Radius arm rear bolt x2	90105-18006
Radus arm axle nuts x4	90179-16015
Radius arm axle bolts x4	90119-16003

Australian market cruiser will use the same parts

When you're doing the work, be sure to only loosen the nut or the bolt that does NOT have the four raised biting marks. They'll be on the flanged bolt heads or flanged nuts and they do a great job of keeping the torque values. But if you turn them then they lose their grip. I think pics of them are floating around here somewhere.....
