After market auto shifter

Scary?

I haven't looked in to them yet. I am trying to decide if I want to hack up a factory console, or just get an aftermarket shifter and build a console from scratch.

My issue is that I have a factory console and shifter (and steering column) to convert my column shift dart to floor. The only problem is that I now have a 518 transmission, which has NO mounting provisions for factory floor shift linkages like a 727 does..so I'm SOL. My only options are an aftermarket shifter, OR see if I can modify the factory shifter to use a cable instead of a linkage.
