Yep just be sure to disconnect the battery first.
And double check it is in the hole correctly when reinstalling and nothing touching what shouldn't be.

The old 123s are scary on the overcurrent protection, the hot feed from the battery goes to the starter, then to the light switch, then the key switch, before hitting ANY of the fuses. There is no way I can get away with something like that in my world (UL 508A industrial controls).
