Recently completed spada resto came to me with this tail piece. I manufactured the seat pad. It seems to have been purpose built for this bike. The front bolt hole lines up perfectly with the fuel tank bolt and the recessed bolt holes on either side align exactly with the threaded holes in the frame that locate the original spada seat fairings. It even fits perfectly around the tail light. Does anyone know anything about a possible donor bike or bodywork manufacturer that may have produced a run of tail pieces for spadas.
