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

karl_desch, I think that you are confusing ''effective length'' with
''overhang''. Effective length is the distance between the stylus 
and the pivot which is by Bearwald 231, 5 mm. On your Ortofon 
headhshell there are slots along which you can move the stylus
in both directions in order to get the right distance to the pivot.

Speaking about confusion, The effective length is 246 mm.

And “effective length” is pivot to stylus; 231.5mm or 230mm is pivot to spindle for FR64S. The difference between the two is “overhang”.
