Help Speedo to NP205 thingy

[CJ5 Convert]

Does anybody know what that thing is called that is some kida of gear convert that goes from the NP205 to the speedo cable. Its an L shaped box and with female connector on one side and a male on the other. I had to replace my speedo cable and when I was removing it I noticed the screws that held that thing to gether had kinda fallen out and it was not closed all the way. I opened it up to check the inside and like an idiot I let the double sided gear in the middle fall out. I can't figure out which way to put it back in. It has more teeth on one side or the other.

Thanks -Jason

Ok I figured out its called a ratio adapter.
