I have 2 Nichimos' one built by my dad (his ride) & one unbuilt, bought as an unfinished project, long before Tacom announced the FV432, my intention was to restore my dad's build.
Both sets of rubber tracks long perished.
I also have 2 Takom FV432's. the parts breakdown makes it clear that they could easily replace everything above the waistline...

So only believe
After I finish some WiPs', I will take the hit & restore the Nichimo, & the CM will make Takom release the kit....
