You need a second reduction box for the rear that is a top shift, ie the stick comes out of the top of the reduction box, not the one that comes out the front
you basically disassemble the donor case and add the bits to the adapter then bolt it all together. You will need a longer front and shorter rear driveshaft, and possibly floor mods
Heres a pic of mine

Heres a link to the install instructions

What transfer cases can you use - reading the sites it says 21 & 23 spline transfer cases, not knowing my toyota gearbox's more precisely which ones are they? Can two LN130 transfer cases be used? Or do they have to be the earlier ones??

you need two geardrive, ie , no ADD or "shift on the fly" bullshit. The rear case must be a top shift, or you need to get a top shift conversion kit from Marlin
The correct transfer has 7 bolts holding the rearmost housing on

and looks like this

the ones you use are 21 spline input shafts, but you can upgrade them to 23 spline 'specially for the rear case if running 4.7 gears
