So I have a 3.9 5mt from a 98' OBS in my 97' Legacy OB. I went to put in a new driveshaft from a 97' outback (5mt), and found that the flanges on the diff were not compatible (different hole spacing). I tried swapping my old rear half to the new shaft but those flanges were different too.

Will the newer BE/BH shafts bolt up instead?
