that is interesting, I would argue that since the PN for the shaft is different for the hybrid it is part of the hybrid system and therefor covered for 8years/80K miles.
a tach (as well as oil pressure) on a hybrid might cause some confusion as it goes into battery mode and both gauges go to zero. It would need to have 'Hybrid' come up in green or something like that. Besides, if you go into the engineering mode you can see the RPM, pretty boring, it stays...
I too have warmed up to the 25 front, but still prefer my 23. I went from that is stupid design by a bunch of 23 year old interns to Meh, I will wait for the next iteration.
I guess you could create your own stops, a roll pin out of the back of the dial and 2 pins sticking up on the back side of the plate, something like this but more elegant
