Ok, now I'll amend my suggestion above. On BOTH driver and passenger sides, you should use a locknut above and below the drop link mount. Now, I just need to figure out where to get 2 more locknuts!!

They got my droplinks to me in two days.
I think some of the guys could get small parts from Carnewal.
And I recall someone wrote that they got some lock rings from one of the big online suspension resalers (ie shox.com or somesuch).

Get the rings
Hey Eric, I think we have met at Grattan b4. You gotta get the extra rings. My 993 RSCS did not have them for some reason and I was breaking rear drop links. now all fixed. Got'em from Bilstein about $60. Good Luck

Eric,
I tried everything, but only had luck with disassembling them, and getting the extra rings from Bilstein. I was really disappointed that they didn't recognize this at first. Since you'll need to re-align, I'd do them both at the same time.

For a while, I was drilling, slotting and installing a bolt to turn them into a "pinch collar" and also continued to use the lock ring.
We found out that the bracket was weak to begin with, as it often would fail on its own, and in a few cases, the bracket failed where I drilled the added hole - stress concentrator. I used a 6mm bolt.
I suggest that you use either blue locktite or sleeve bonder and position correctly with a properly tightened lockring. The extra lockring is a great idea and probably the right solution.
Regards,

Any way to let Bilstein know this so they would include it as part of the kit to begin with?
Using double lock rings seems the only good solution I've heard. Someone had suggested earlier to just run the mount down to the end of the threads and then tighten the lock ring on top of that. Nice thought, but the trouble is the orientation of the mount won't be what you need unless you get incredibly lucky.
Save yourself the trouble and don't bother installing w/o double lock rings in place!!

As a follow-up, the Bilstein part number for the individual locking rings is 420926. They are about nine bucks and change each. They seem to not be giving them away gratis anymore....

If you have one of the early sets of PSS9s, they only have one lock ring. The improved sets have both double lock rings and the "hats" for the rear. I have tightened mine as much as possible and used Loctite Glue to hold them in place. No movement in 3 years of DE's.

On a related topic, is the mount spinning issue something one is likely to see with HDs?
Or, would the drop link mount not be as prone to movement since it is loaded by the spring?

You will need to file 1/8" off the sloping shoulder on underside of the drop link attachment castings to get the extra lock rings to ride smoothly. In my opinion, unless you wish to go lower than RS height, you should use the lower lockrings, ie one above, and one below. When the strut is installed, the lower lockring is really close to the rubber boot on the driveshaft, so check this clearance and if necessary adjust up a couple of threads, or file the lock ring.
