1979 Bronco Ranger XLT, 400m engine, C6 trans, D44 front with Dick Cepek manual locking hubs
It worked fine!
However if you have the front clip installed I am not sure the engine can be lifted high enough, maybe it can work if you put the lift on the 2nd last position (1 ton mark) - for me it was no problem on the 1.5 ton mark, same is planned to be used to put the 460 in.
the gearbox should be been rebuild late 2009, so I am still not sure if I need to open it.
Leaking oil at the neutral safety switch, but changing that o ring can be done from below.
