727 Noob

I'm totally ignorant when it comes to transmissions, so I'll explain this the best I can. I'll try and post pics when I get home.

67 Barracuda 383 w\ TF A727

The guy before me removed the original shifter and mounted a Hurst shifter further back over the trans tunnel. The shift cable runs down to the two levers on the transmission but is not connected to anything.

One lever is tied off with bailing wire??? (rednecks)
Can anyone explain what the two levers do? I assume one of them shifts...lol

THanks,
Wes
