^^ Close but not 100% accurate.

The plastic speedo drive gear inside the gearbox will require changing while the case is split, the external sensor has nothing to do with calibration.

The centre diff, viscous coupling and the transfer case remain as is, you will need 1 to 1 transfer gears from a gearbox of the same era as yours. Early 4 bolt case boxes have a different coupling spline, later ones (post ~00) have tapered bearings (yours should have ball bearings)

Also, check the gear ratios of your Albins kit as well, you may find that it's overall geared too low for 4.44's. If you have the set with a 3.45 1st and a 0.97 5th, they work best as a 4.11. If you have a 3.08 1st and a 0.87 5th get some 4.44's in it!
