Well Moss has a lt lead that will work with that plate but when I go to switch the 1 month old points/condenser from the old plate to the new one I find the new one doesn't have a pivot post for the points assembly  grr.

So now I have to pay shipping for new points ('cause they didn't tell me that when they explained the plate difference).

It appears from britishvacuumunit.com that that part along with LU54413549 (moss 153-640) might work, although it's not clear from any of the photos if that terminal connector is meant to fit *over* the fork of LU421078 or *instead* of the fork.
