I wanted to see what the OEM Toyota Clutch looked like in comparison so I ordered one.
Part Number 31250-60110 which is replaced by 31250-35410, so clutch number 31250-35410. Not a cheap part.
It is made by AISIN but does not have a legible part number on the actual Disc.
Here is a side by side comparison picture of the OEM and AISIN Aftermarket that comes in the clutch kit.
The OEM is physically heavier, springs are different and it does not have the plastic retainers on the springs. Also the there is more spline engagement on the transmission.
Talking to several friends with Toyota's all of there first suggestion was to get the Marlin Crawler setup and be done.
Hoping supply chain issues get worked out soon.
