If you don't want to move the crossmember forward & modify driveshafts, you need this:

The transmission has to be torn down to put the shaft in though. As I think was said earlier, I think there is a stock length output shaft from a long tail 2wd that comes close, but then you have to do the crossmember & shafts rework. Or, I think there was an oddball "extra long" tailshaft in some vans or maybe subs that would work with the aftermarket case spacer.
