Rick Williams is looking for a rear brake adjuster for his Midget Mk 2.
He is chasing like a genuine second hand one after buying two new ‘reproduction’ ones (pictured); however, the threads bind and cannot screw in from the front. He’s seeking one to complete his brake overhaul.
Can anyone assist?

Perhaps we could put it in the lathe and run a thread file or die nut over the new pair to make them fit
I would be happy to try
