Thanks but I have sent some PMs to various people on here who post in the 915 transmission threads asking for help but I didn't want to pester them.
Maybe this tool is rare considering what I was told this morning by the independent Porsche specialist (see earlier post)

I did stop into a transmission only workshop asking for advice and the mechanic there was very helpful.
He said the the R&P backlash on almost all cars is measured at the edge of the "Ring Gear"...
Only some 60s model Fiats, Alpha Romero's and Ferrari's are measured at the "middle" of the crown teeth.

Meanwhile I think I'll be making an adjustable version of the tool so that I can move the dial gauge if needed.

My tool will have a range of adjustment of 75 to 95mm. I'll post some pics when finished.
