Patrick,
If you look closely, the positive and negative banana terminal are part of an entire assembly. These are the same that are used in the TIU. YOu might be able to reassemble that dual terminal assembly to replace the single damaged binding post but once you have the Z4000 apart it may be easier to replace the whole thing.
See my picture below: The one on the left was removed from an early defective TIU and the one on the right is a replacement from Radio Shack:
You can buy the entire replacement assembly from radioshack.com: https://www.radioshack.com/search?q=2740718
Tell you what, send me an email with your address and I can send one that I have salvaged from a TIU.
UPDATE:
Yes they can be completely disassembled see below:
