SRM ordered a replacement 9200 ring and ground down the pin to a length that is compatible with their cranks. Kudos to them. I was able to be the bolt out of the NDS cranks arm with the help of my LBS.
Once I receive the new chainring I’ll install and verify not contact with the crank arm. Then use my very precise Wera hex driver to install the NDS crank arm. The replacement bolt they sent installs just fine at 5 Nm if I use the Wera driver.
