I realize that the F6B hand rails would not fit using a goldwing seat. And the two seats differ in the rear.

But, I gotta believe that the frame/mounting holes are the same. That is, the four main mounts - forget the two rear ones. I have mounted a goldwing backrest that uses those four bolts. I use it on long trips.

So it seems that a goldwing seat would set on an F6B frame and bolt on, and leave a gap at the rear. Will it do that? If not, why not?

This is just a curiosity itch that needs scratching at this point. Thanks.
