These pics are of the optional King Queen seat for the respective bikes.
The seat pan is the same. The other difference is the thicknesses of the rubber bumpers that contact the subframe, I figure that will be pretty easy to figure out. But I could get those dimensions if you want. And the Metal hooks that capture the subframe.
In these Pics the front of the seat is toward the left.
Looks like about 37 mm center to center for the mounting rivets.
The little rectangular plastic pad where the pin sits on the TBird seat is 4mm thick.
