NOW I remember them... fragile miserable buggers to install!

Can you try this???
Lube everything up with enough soap to clean a week's worth of dishes...
Take a VERY long and even-
more-very-thin screwdriver and reach through the puppy and kind of hook it on the edge of the grip...
That might help get things started. CAREFULLY work the screwdriver around the circumference of the opening... keeping in mind that a wrong breath of air will tear the puppy...
A very tense two minutes might be the answer!
