Technical 56 plate gearbox

[vaughanpreece]

hi all. i've been looking around for a 5 speed gearbox for my 56 plate van with very little luck so far.the only ones that i have seen near to me have been the 6 speed version out of a 2007 model.im wondering if the 6 speed will fit straight into mine..or if anybody knows where i might find a gearbox it would be greatly appreciated..
many thanks in advance
