R151F gearboxes

[dvk-kp]

Hi, recently got my hands on a 1KD KUN26 hilux. Looking at a few adaptor options for different engines and there’s 2 different input shaft lengths for the R151F gearboxes.

Can anyone confirm that 160mm input shaft is from a 1KZ hilux, Prado etc and 190mm is what will be in my hilux? Most adaptors work with 160mm.

If I’m right, is there any issues putting a 1KZ gearbox into my truck to suit the different engine? Eg transfer on the opposite side or just something like they won’t work with my 4wd system?

Thanks
