A member once posted a link to a European pinball site that made/sold SST mods for the Terminator 2 pinball machine. Of course I can no longer find the link. If anybody saved it could you please repost it.
sample pic of their work is attached.
Also, I did find somebody selling what looks to be the same items on Ebay so I've sent them a message looking for extra info. Hopefully It's the original makers.
