The cheap way is this polish webshop that sells the driver in a steel version separately. They only answered my emails (havnt bought anything there yet) when I sent them pre-googletranslated to polish and got polish answers. http://e-bmx.pl/opis/565772/bebenek-kasetowy-bmx-cs-do-piasty.html
That is the driver from the novatec F176SB hub if you want to find it elsewhere.
For the main hub body d042 is good because it is a chunk of metal! and has a 12mm axle and large flanges. You need to pair up the hub + driver with either 28x12 or 28x15 bearings depending on the hub + shorten the axle somehow.
A lot of other novatec hubs could work as well looking at the specs/drawings (but needs to be confirmed...)
The amazing thing is d042 + short freehub & endcap from d252sb gives exactly 120mm! Axle needs to be tapped with more thread or a new shorter custom axle.
