...a windage tray AND a "car type" tailshaft ? in a truck package ..

This is probably the best-case example of odd-ball combos that Ma Mopar has put together !

I haven't seen the windage tray part but the rest is pretty common including the long tailshaft transmission. These were found on 2 wheel drive standard cab 440 pickup trucks and some of the van type 440 equiped RV's.
I have the transmission right now out of a 440 equiped 74 standard cab 200 and the 440 had the 6 pack type rods and the forged shaft in it. It was a virgin.
