maz,beigy will have a diff thats commonly refered to as a small 10 bolt..beigy is wb correct?.
the gears in a small 10 bolt are the same as a banjo but fine spline axles..no burnouts and no major acceloration and it will hold up..your tailshaft is already a v8 configuration as all wb came like that...so all else is as i have stated..whern you get to it if you need any advice just call...or send pics...:Chin:
