was doing a little bit of bench racing in my head when i came up with this:

one 700r4
advanced adapters main shaft to make the rear output of the 700 r4 work like a th350
th350 to np203 adapter
np203 range box from behind a th350
a northwest fab 203 to dana 300 adapter with a 32 spline output.
32 spline input np241 from a th400

doesnt the dana 300/np231/np241 all share the same bolt pattern?
this seems like it would also work with a np208 but who cares.

am i wrong?

*EDIT*
I searched it for you. After I posted I remembered I started asking about a 271 so it might not have come up.

The D300 shares the pattern with Jeep and Ford 6 bolt rotations, the GM NP205 and NP241 also share the same pattern, but at a slightly different rotation.

We have mated a NP241 to the 203, it does require a different adaptor plate as we integrate the bearing retainer into the adaptor, but the price remains the same.
