ok your transfer will bolt up fine to a manual box you will have to change your rear shaft but the front shaft will be ok but i think the gear box X member is in the wrong place you will have to check also the 1hz and 1hd-t boxes are different in the gear ratio

how come you wont have to change the front shaft as well? the whole transfer moves forward due to the shorter gearbox

yes transfer is the same and can be reused

cross member needs to be moved forward

gearbox ratios are different on a couple of the gears but does not really matter
the main thing is that you fit the correct clutch if you get an NA diesel box you will need a custom clutch with a fine spline to match the input shaft
