On the nozzle display unit, does the main round discs (two discs glued together) that the nozzles are glued to not recess some up into the base of the 1b main tube? As I recall on my Centuri 1b, that is the way it is ‘held’ into place...friction fit from that disc.

And the section of ‘body tube’ glued to the other side of those discs - opposite the plastic nozzles - keeps the entire display unit from pushing all the way up into the base of the 1b. Possibly THAT tube is too ‘tall’ and not allowing the main round disc to slip a little bit into the base of the 1b.

Just some thoughts....
