Stew.. you sure about that? Or am I misreading your post?
The single piece seat and no back rest pillion handles were introduced in 2005.
You can mix and match them, like your 2008 shows. But the pillion handles on your 2008 bike are not 2008 pillion handles! You (or someone) put those on.
Here are links to the fiche for the 2004 and 2005 models
2004 has the split seat and back rest.

I have read that the bolts that mount the pillion handles are not the same length, but I can't attest to that. The Suzuki PNs are different.
So:
You can mount a backrest on a NEWER (2005 and higher) bike if you get the pillion handles, backrest, etc.
You CAN NOT mount a 2 piece SEAT on a NEWER bike because the fender doesn't have the right mount points.
If Cushman is OK keeping his one piece seat, do that and put on the pillion handles and backrest from an older model.. just like you did!
