You can replace them in three ways:
1-Use individual caps and terminal strips. Negative for all three caps is common. OK to reuse this, but you must disconnect the positives for all three from the old cap. Leave the old cap in place for appearance.
2-Replace the guts of the old cap, and put the new ones inside. This is known as "restuffing" and a bit more advanced.
3-Try to purchase a replace can type electrolytic capacitor. Not all values are available, and they can get pricey sometimes.
Usually easiest to go with option 1
Thanks, Guess option 1 it is.
