To run dual cases with your V6, you will need to buy an adapter for your transmission to adapt to a gear driven transfer case to it

then buy/build your your dual cases using 23 spline input gears for both cases.

Another option would be to find a 5-speed and transfer case out of a 22re turbo truck, as the trans is an R series like the V6's, and the transfer case uses 23 spline input shaft from the factory, then you would only need to buy a 23 spline Crawler Box, but they are rare and pricey now.
Thanks for the reply Snowtoy.
1. When you say an adapter, you refer to an adapter that alters my transmission bolt pattern, but where can I buy that adapter?
2. When you say buy or build my dual cases with 23 spline, you gave me this link (
https://www.marlincrawler.com/transfer-case/built-units/hilux-gear-drive/dual-case-complete), but that is for 4cyl and I have a v6 case, wouldn't this be the appropiate link (

Thanks for the cooperation.
