Hi Guys

I have a GV1600 3Door with 5.12 diff's and and 30's... I Really want to ride on 31's or a 32's

I have 3" Bodylift and 2" springkit...
I myself am a panel beater, so space for the wheels is not a problem
But i really need lower gearing all over... now with 30" I think that it is too highly geared
Can I install another gearbox from the older Vit or something??
