Rob, I'm a little confused...
To mount a sliding table (like an Excalibur) to a 64a, you remove the left extension wing, and cut off the Accufence rails flush with the table. Then mount the slider. In this picture:
http://www.powermatic.com/catalogs/s...mages/64ta.jpg , if you squint just right, you can see the seam between the main table and the extension, that is where the slider will mount.
On a TS2424, you can do just the same thing, remove the left wing and cut off the fence rails.
http://www.ridgid.com/woodworking/pr...TS24241_bg.gif is not quite as good a view as the Powermatic pic, but still you can see the wing's location. If you wanted to, you could also slide the rails on the Ridgid down (I think you would have to drill new holes for the rear rail?), and have a longer than stock fence, you would of course have to replace the measuring tape.
I prefer not having T-slots myself. Removing a miter gauge from a T-slotted saw gripes me to no end, but I realize many people like them.
"less than average left...rip capacity" If you mount a sliding table, your left rip capacity drops to zero...

Left rip isn't much of a necessity on a left tilt saw anyway.
My Jet 18" bandsaw uses the same spec motor as the 64a. I strongly recommend wiring it to 220v, on a 110v 20a circuit, it can easily throw the breaker.
