Broken speaker terminal, Dunlavy IVA

Just broke a speaker terminal on one of my Dunlavy IVAs. Anyone know what the manufacturer and model number for a replacement? Or, should I replace them all with better quality? Also, how easy to replace? Thanks!
Replace them all with a good quality post, and solder the wire to the post. The crossover with the terminals unscrews and can be pulled out of the speaker. I would also flush mount the board that holds the post so that you have much easier access to the terminals.

Never had any problems before as I was using high quality bananas but broke the terminal trying to install Virtual Dynamics Revelations with spades. Yes, I think you're on to something with the flush mount board idea. May have to fabricate something. It sure would make life easier. How about turning the board inside out? Thanks Robbyg!
