Cruisin' on my Bluebird
Glad I could help! Being a retired mechanical designer, I've been puzzled as to how the seat springs would attach to that rear piece ever since you first posted the photos of what you had. Finally figured it out after seeing the dog photo...I think. I believe the whole spring assembly is made out of one piece of spring steel wire. The wire being a large enough diameter to snap into that rounded groove, bent 90 degrees back on each side of the groove, and then curving underneath the horizontal piece behind the groove on up through the coils. The horizontal piece would act as a stop when coil tension load was released but allow the coils to flex when under load. If that makes sense when you look at it.Thank you so much @ridingtoy , that is exactly my bike. I appreciate that you sent me this. That is helpful.
