Paul, that explains the difference.
Smoffat and yourself have Phantom II's. I have mark1 and the left side of the headshell is symetrical with the right, hence their being a gap on both back ridges with mine.
Yes Shane, I thought that would be the case.
I too have the SME base - so could adjust the base and cartridge position so the ridges contacted. I can't really be bothered going through the realignment process for what I suspect will be zero change sonically. At the moment 2 ridges are contacting and the third contact is with the cartridge top rather than the other ridge - no big deal IMO (as long as azimuth is compensated).
However, if you decide to experiment and find some dramatic improvement - do report it here!

I was trying to be factious with the grinding off, if your tabs offend you, cast them away etc. I myself would not obsess about all three touching at the same time but then I don't spend hours aligning cartridges. I have been setting up tables since 1962 and somehow seem to get them to work. I was serious about the Blutak,
No worries Stan.
Regarding the blutak - that's not something I'd employ with a high performance cartridge like the A90. That would seem to be the exact opposite of what is being sought with the ridges, ie a coherent rigid coupling for extraneous vibrations. Then again, things like the Cartridge Man Isolator works for some people, so who knows.
