The W50 - Toyota Steelcase can be found nearly anywhere here in aus as there were used behind so many holdens, fords, chryslers ect with 6 or v8 they cheap to get your hands on much easier to find and use then a crappy t50, albeit alot cheaper then a T50 as well cause they are so readily available

Strong boxes, dellow conversions sorted out the bellhousing for me and we used a holden W series clutch fork that is cut down as they very long and welded. The bearing carrier was machined for the thurst bearing

The bellhousing, pivot ball, speedo gear, clutch fork, gaskets, weld on yolk, uni joint, slip joint ect cost me $1700 from dellow jeff is a great bloke and was always willing to help out.
