Is the fishtail socket for oo guage nem adaptrs available for retro fitting? I need to use the flexible nem adapter for close couplings. Tried gluing a fixed adapter to bogies but need the flexibility on curves to stop coaches from derailing. Rob.

If I understand this correctly "Fistail NEM" would be the type that gets longer on a curve? I too am looking for the same solution. The extending NEM sockets are superior to anything used in N. America and you can get Kadee couplers for NEM sockets.
Don't know if it's exactly what you're looking for, but you might want to check these guys out:

The Symoba 111 NEM Conversion Sliders (kinematic coupling) allows body mounted pockets to swivel on sharp curves.
