HZJ105 Gearbox (r151) swap into HZJ75

[Spudnik]

Hey guys,
Does anyone know if its possible to put the 105's Gearbox into a HZJ75. Im able to get one pretty cheap and am just wondering how much work it would be or to just put it in the too hard basket.
Do they have different input splines?
Does it even fit?
New tail shafts?

Thanks guys.

Troopy or UTE?
Think on troopy will easy.... don't know is center tube reforge it little back alignment.

On Ute not easy dude, needs to modify center tube reforge and modify fuel tank. A lot of engineering.
Not sure final result.

My opinion buy +99>on LC .... more easy to make the swap and confort ride (front coil).

PS... Actually I deal with this problem. HZJ75 '92 (hd-t ready) Ute but i try to update in frame hzj78 '02 (H151f + hzj80 diff) ... and I think I waste time and money.

Maybe give up at the end of the year

You will need change the gear shifter and low range stick from 105 to 7X series , gearbox cross member is in a different location, the floor holes are wrong you need to unpick a 79 series one from a 1hz version and unbolt the 75 series one , lots of work for a weaker gearbox
