Fidelity Research FR64s Headshell dilemma


Dear FR64S users can you help me please. I have an FR64S that i bought without a headshell. I have only just got round to getting it mounted. I did pivot to spindle distance of 231.5 (the alternative distance' I also have an armboard for 230.
I tried a Sony headshell that i had - it was 2mm short of correct alignment. So I bought a new Jelco headshell it was also too short. 
CAn you tell me what headshell does work to allow other cartridges to work. I'm just using a DL103 for alignment first as I fettle the rest of my front end.

thanks

Using FR-64fx tonearm I can put my FR-7fz or SPU on Dr.Feickert and the cartridge body is perfectly aligned according to all lines printed on my protractor (for cantilever and cartridge body alignment). The stylus tip on FR-7fz or SPU is on cross point of Stevenson. This is 100% accurate and sound is simply amazing. This is all i have to care about, thanks to Ikeda-San.

Enough said.
Anytime i have new tonearm and cartridge i follow manufacturer recommendation only, i trust to tonearm/cartridge designer more than to anybody else!
The experts once thought the world was flat, too, until someone ventured west, and was stunned to discover they did not fall off.
Until i will be actually HEAR there is a problem i don’t care about all these pointless theoretical speech that one alignment is better than another.
This reminds me of an old doctor who received a visit from an attractive lady. Upon asking her why was she there, she said to him "I have acute angina". Unfortunately, as he was hard of hearing, he lost his license.

Dear dover, what does ''I have acute angina'' means for an
deaf person? Some foreigners among us have no idea why the doctor ''in casu'' lost his ,uh, license. 
If to look into details you'll find that  the world isn't perfectly round. But devil is always in the details. 
But better to believe in round globe. 
Although of course 0,001 mm is very important as feeling of mindfulness can be lost.
16.863 or 15.948 that is the question for the doctor.
Stevenson alignment was the latest BTW (after Baerwald and Lofgren).

I know for sure that people lost their hearing abilities at certain age, i must admit i am far away from that age.
