So here's a related question for you: On the bottom of the RA axis housing, just below (behind) the RA lock knob and the worm gear shaft, there are three hex screws. The outer two are the small thin type that look like they're holding something on or together, and should not be messed with. The center one has a big, bright, inviting, shiny metallic head. Is this center one used to hold the drive motor on, or will something horrible happen if I loosen it?

I'll have to take a look, but I'm pretty sure it's just the one shiny allen bolt that holds the motor in place. I just upgraded my GP mount to a Vixen motor that I was lucky to find cheap. I removed the Orion motor by loosening that bolt - pretty sure the SP is the same.
Here is a pic of the GP with the motor installed. You will note that it's not a perfect fit as the motor sits at an angle.

If you have a cover over the RA mount point, take it off and see if you have a hole through the mount for the motor screw. If you don't you may need to fashion a dovetail mount bracket to attach one of the motors made for the newer style mounts that only used the single screw.

I went ahead and ordered the Orion TrueTrack drive from Adorama, but it's backordered so I probably won't get it for about two weeks (probably will be ground shipped from CA to NY first. So much for ordering from and East Coast place!).
Thanks again everyone! I'll let you know how the installation goes.
