it's good if you plan on rebuilding your diff as well.

what you would be looking for is a "master bearing install kit "

the rear end is pretty simple on a car.

you basically have:
ring and pinion (gears)
Differential
axles
there are other things but those are the main parts.

the bearings is the difference and YES you need them.

esp on a car as old as yours man.
think of it this way..
$150.00 extra for the kit now or another $500 PLUS another $150 for ANOTHER rear end rebuild when it breaks because the bearings were old.
