all gears out of VB-VS will fit, 25 or 28 spline axels, IRS or live axel, LSD or open centre. the gear set is interchangable.
also some other BW diffs have gears that are interchangable, but not sure on which ones.
just go and get yourself a shitty stock VL 25spline single spinner diff and rio the gears out of that. thats what i did (thanx to a generous member here
) for my VP SS
