I restore those can type caps by putting them in a lathe, cut the rolled edge off, remove the guts, save the metal grounding ring and solder lug ring from the old cap, clean out the inside, 3D print a spacer to hold the required radial cap centered with airspace around the outside (this keeps the new cap from flopping around inside the can), 3D print a bottom plate of suitable dimensions to hold the old solder lug, place the new cap inside with the leads protruding from the appropriate holes, re-roll the lower edge of the can to secure the assembly and then solder the leads. Makes a perfect OEM original looking replacement part with a modern cap inside.
