I have a rare Ford alloy gearbox crossmember here which fits the MT75 4x4 box into the narrow 3dr tunnel - a normal 3dr one or saff 4x4 one is no good, people usually swap tunnels or fabricate a crossmember, this one allows the original tunnel to remain, you just need to cut out a small section of tunnel to allow the transfer chain case to fit. Let me know if your interested in it.
