bulldog,

From what it looks like you should be able to adapt a Hurst shift lever (available in a bunch of lengths) to the stock stub. Looks like a flat side and two holes, might need to fab some bushings. Here's a link to a guy who says he did it; http://webpages.charter.net/1bad6t/tremec.html

The Tremec site advises using the front locating position for "hot rods", but the mid location for truck retrofits. I'd suggest you mock up the installation, set the seat location, and then decide. That way you won't have to cut one of those notch outs in your seat that makes it look like an after thought, or be stuck having to reach too far forward to shift. Also looks like you'll need a kit from Tremec to use either of the forward locations, as it appears the rear location hardware won't transfer forward. Here's the Tremec manufacturer web site.
