Dan is right on this. The box and the linkages provide somewhat of a good start, but the bell housing and driveshaft parts are also required. W/o the driveshaft parts, you could probably have someone cut down the stock one or perhaps even use one from an A/T set-up--I heard it is shorter, but the bell housing would be the real problem in finding. Michael Egan, in his own conversion effort did some great research on what is and what is not available for these boxes. Basically you can find many of the bearings, seals, attaching harware, gaskets and other incidentals such as studs and shims since these in many cases are std DIN items, but pretty much forget about the gears, shafts and any of the castings. The Maserati Club(I believe it is in Oregon or Wash State) can provide manuals that describe assembly/disassembly of the S5-20 that was used on the Maserati's--a very close cousin of the 113 box, but has a different top linkage and driveshaft connection. Anyone interested in bidding on the box should ask the person auctioning it what happened to the bell housing and other parts--perhaps they removed to facilitate shipping not knowing they are essential conversion items.
