The 66.63 on the original r&p was the ideal pinion face offset from the diff's rotational axis, as I think you surmised. Getrag/Porsche shifted to providing that value later in the 915 lifetime. I have a '85 Euro 915 box on the bench with this absolute marking rather than the N deviation.
Are you confident that your VW 289 is reading correctly? I'd offer to compare it to my VW 385 set measurements, but you're a bit distant and shipping may be expensive.

hi Kevin
short answer = NO, I am not confident I am using it or reading it correctly!
Going to take it to someone else in coming days for second opinion.
The tool belonged to Evan, and he used it to set up his box and from what I can tell it worked well.
I plan to use some gear compound too before I pull it apart, just to see...
