bush devil/ ford pickup

[tamiya monkey]

Hi wondering if anyone has either tried this or have any ideas, i want to make my bush devil into a kind of cheap ford ranger truck, want to keep the newer gearbox of the bush devil but info on shorter arms and drive shafts etc, for the front thought of putting a frog/brat front end on but dont like the setup prefer something softer with more travel, did not know if i could put a king blackfoot front end on with shorter arms again, any advice would be a big help.
