Well, what conversion are you doing?
If you are sticking with 95 headlamps, use the 95 locking rings.
If you are converting to 96/97 headlamps, use 96/97 locking rings. You can get them from either Dan Newman or a junkyard.
The 95 locking ring will not work on the 96/97. Tried it myself. Doesn't work.
