Gearbox HZJ75/78/79

[zigzagcruiser]

Hello
does anyone know if it is possible to replace a HZJ78/79's gearbox the R151F by the HZJ75's gearbox the H55F ?
And are changes to make?
Thanks

Hello, it can be done. U can refer this thread >> https://forum.ih8mud.com/70-series-tech/143839-operation-soa-75-a-8.html ZOLTAN is using 105 series 1hz engine which is the same as urs with the EGR system on it.

I think one of the problems you would have is the H55F is shorter and the crossmember will interfere with the leading arm of the front suspension on the 78/79 series. I guess there are ways around it.I havent read all of Zoltans posts
