Bogie mounted Tomix TN couplers?

[Welshbloke]

I've been digging through my handful of older Tomix locos and coaches of late, adding headboards and working out how to rid them of the Rapidos. Obviously the 0391 pack is right for the coaches (bogie mounted knuckle couplers) but I've also found 0392, described as "magnetic". Are these to replace loco couplers which swing upwards when over an uncoupling magnet? They look very similar but I can't find a fitting guide.

Right, for anyone else struggling with this, you need 0392. Not entirely sure the "magnetic" part will work as the new couplers don't seem to swivel upwards like the old ones, I'll have a fiddle around. They do stay attached to the bogie but the problem is that the coupler is separate from the part which clips into the mounting holes (which is supposed to allow it to flip up magnetically). My old EF64-1000 and EF30 will be able to haul my passenger stock.
