Will'* seen one, and I've seen 3 or 4 (mostly on E-bay), but no a leather bench seat from a Bonneville won't fit in a 1997 GP unless it is one of the VERY FEW SE'* with bench seats. As Will stated ^ ^ the base mounts are no doubt different, but you might possibly be able to make some adapter plates to use the GP mounts with the Bonneville seats.
I'll go take some measurements on the mounts from bolt-to-bolt on my Bonneville and when my sister get'* home from the grocery store I'll get measurement'* from her GP.
Hopefully I'll have the info available in the next 10 minutes.
