That's a multi-section capacitor, not wholly dissimilar to the one in this post:-

Your best bet is to "restuff" it by fitting new capacitors inside the can. You may be able to lift the Paxolin lid slightly, snip all the wires off its underside and then dig out the contents of the can. This will save a lot of unsoldering and resoldering of wires.
The figures on the Paxolin show quite clearly which caps go where. Any capacitor of more than 1uF is likely to be of the electrolytic type and therefore polarized. Their negative ends will likely be connected externally to the chassis, possibly by the long bare wire linking several terminals.
Lower value caps are not polarized and can be connected either way round.
