Why no toyota trans to 302 adapter?

[Offroadman83]

I love my doubler with 4.7 behind my 22r manual but it's brutally hard to follow in between trails and what not. I've gathered an aw4 with a340 bellhousing so I can swap to a 4:1 dana 300 and I am debating on a np231 doubled to it. Not sure what gearing etc in axles or what I'm gonna need or like but I miss my auto rigs.
