I'm not sure just how helpful this is, but for my FS78 focuser the Borg adapter that matches the rear threads is called M56, so I am assuming it is a metric 56mm. You may check the Borg (Hutech) site under part #7911 to see if there is more information on the exact threads.

Borg part numbers 7911 and 7502, when combined, get you from the rear threads of an FS78 (and I believe the FS90 too) to a male 2" SCT threads for using SCT adaptors.

Another source of help may be Art at Land Sea and Sky - Texas Nautical Repair, the US Takahashi importer.

Hope this may help you find the info you need.
