PLT, its possible to make cable shifters work great... but they are not a cure-all. As I pointed out on the POCA Forums, the Pontiac Fiero used a cable shifter and also the late MR2s; I've had $150 MR2 cables break at the clevis due to a minor(?) factory misrouting. When that happens, ALL gear selecting is stopped. Some exotics that use cables semi-successfully are the '70s-'90s Porsche 911s and 914s; the complaints are usually of slow, balky shifting. The exotic $250,000 Mosler MT-900S and Photon mid-engines use a cable shifter, and in a recent track test (which they dominated), the cable was too close to the exhausts and burned/melted, radically slowing all shifting. Watch your cable routing!
Balky shifting in Panteras usually comes from either mis-adjusted shift linkage, from slam-shifting too fast which overwhelms the synchro rings in the tranny (same as with Porsches), or from clutch hydraulics & mechanisms so badly worn that they in turn have worn out the synchros in your ZF. With all of these, changing the shifter type will not replace missing metal....
