well i decided to go hunting down a diff to do the conversion on the weekend but the first wrecker that i went to (that specialises in toyote hilux's) said they haven't have RN40 series hilux's in for over 15 months, but they have LN60 series ones and plenty of them.
So is this also an approprite diff to fit into the RA40 or does it definately have to be the RN40 series.
Also I wasn't aware of how much of the diff i needed so they quoted me the for the whole assembly (included drums handbrake cable housing and centre). How much of this do I really need cos they said it would be about 400 dollars which was more than i expected.
From what i read from GiantTomatoe's website (and Cool1's post) if i was to convert the diff straight away to have the supra brakes on it then i would get all the brake components from the supra and just the housing and axles (no centre because that would be the wrong ratio and setup or handbrake cable) from the hilux.
Argh these things i have never attempted to play with before...so confusing.
