I'm not sure if anyone else has bothered with this.

As I was installing my RD-1C PSRU, the instructions note to take special care to align the spacer blocks that have only one bolt and make sure that they are snug as they can rotate and hit the ring gear teeth. I thought "What if one of these bolts loosens up in flight?" So I drilled, countersunk, and tapped two 8-32 holes though the mounting plate and into each of the two "one bolt" spacer blocks. I used 1 inch long screws with Locktite.

I figured, no harm in pinning the spacer blocks and it doesn't take much of an effort. Why not do it?

Attached is a picture.
