How to extend a wall tap spindle?

[Samviv]

I have recently brought new mondella pin lever 1/4 turn ceramic taps - https://www.bunnings.com.au/mondella-black-resonance-pin-lever-wall-top-assembly_p5004187

However once installed we don't have enough spindle left to properly attach the cover plate, tap handle and secure the screw so that the tap handle doesn't fall off we are only maybe 2/3mm off it working (the handle can be attached without the cover plate).

We tried to use these spindle extenders but they don't reach to the seat at the back of the tap, so the water constantly flows.  https://www.bunnings.com.au/kinetic-28mm-ceramic-disc-spindle-extender-2-pack_p5050142 

Does anyone have any ideas of what we could use? I cant find any spindle extenders or longer spindles that are the correct style for these taps.
I need these but in a different style? https://www.bunnings.com.au/kinetic-20-25mm-spindle-top-extender-4-pack_p5050144

What I ended up doing was sanding down the handle by 15mm on a bench sander. Just being careful to get an even sand. Losing some handle was ok for me and still looked fine. No extenders, seating problems, sawing required. I wasn’t going to buy $40 parts for a $99 tap set. This was the most elegant solution.
