you can get 4.11 gears from a nissan pintara rwd(4 cyl skyline), and the 3.89 from a r31 skyline..
both cars are borgwarner diff and the gears will fit into the falcon..

thats what the diff guy said and quoted me $1975 fully installed
and think thats a bit steep or is that the normal price
I thought it would be a straight swap over even if the gears cost me $600 why is it so expancive to have them installed
cheers Dan
