The diffs are bolt in, but the driveshaft needs to be custom when using a different trans vs diff. (tii trans to n/a diff, or n/a trans to tii diff)
And you need to use the axles that match the diff. (tii axles on tii diff, n/a axles on n/a diff)

Different series doesn't matter.
As a reference for TII diffs I believe
S4 = Clutch Type LSD
S5 = Viscous Type LSD
