The nominal hex dimension is 32mm; the tool pictured below measures 31.90mm.
This has been the primary backlash tool, since the mid-1970's, for all Porsche transmissions.
A couple of corrections to earlier posts... This tool does not use the locking washer from P357; it uses the Porsche adaptor sleeve 9145. The sleeve P365 is not a metric adaptor, it's an indicator standoff for measuring 905 Sportomatic pinions.
