    Pretty sure they wont...
    VT series one had the BW78 gears, and series 2 upwards had the BW80 gears

    They will not fit
    all the ones on eBay are for the smaller diff VT series 1 and ecotecs
    from VT series 2 and VT series 1 L67's they use the larger diff
    if the add says suits vl's and up to series 1 VT forget it.
    i nearly got caught recently just went and bought a new set of 3.9's

    Being a 5.7 do you mean the GENIII (being a series 2), or the holden stroker 5.7 (series 1, in some HSV's)???
