Heres some NOS in the box 1967/1968 Hella 12 volt Blue-Boxes. These are the emergency flasher boxes for 1967 and 1968 USA Buses, I don't think European Buses use these boxes. Made by Hella of Germany and no longer made. VW part # 211 953 227. These fit 1967 & 1968 Buses and VW Trucks. These will work in 1966 Buses when converting 6 to 12 volt. Nothing like NOS VW parts. $125 each plus shipping Thanks for looking
