4x4cossie
doing this conversion myself and trying to get prices together too.
i'm doing a project thread on here,have a look what i have bought and you will need similar items just to handle the cossie power.
prices are starting from £2500-£5500 just for fitting parts that i have bought.
this is not full group 4 spec either.
you won't get this work done just by anyone,needs to get someone that has done all this before etc....
hope you find someone cheaper than me,lol.
