The negative of the new cap(s) connects to whatever the metal housing of the original can connected to...
Many cans were soldered directly to chassis ground, but others rather than connecting the can to ground, connected it to a floating negative rail.
The original can will have 3-4 outer twist tabs coming from it's bottom...If the twist tabs contact and are soldered to the chassis metal then the can is grounded to chassis....But if the twist tabs are twisted onto a phenolic insulating wafer (the wafer is riveted to the chassis in 2 places) then the can connects to a floating negative rail (and your replacement(s) should then connect to the floating negative rail instead of the chassis). Another giveaway that a can is on a floating negative is when the metal can above chassis is wrapped in a cardboard or plastic insulator.
If that is confusing then ask me for some pictures tomorrow...Visual aid makes my point come across with at least a thousand fewer words.
