I've been fixing up a ~1972 Raleigh Gransport but have run into an issue with the headset. When I took it apart, I was certain I put everything in a cigar box together. But, now am having an issue. I have 4 parts to put on it, the threaded top race, a spacer, the locknut, and another piece. This other piece is the guide for the brake cables, I'm sure you've all seen them, but I'm not sure of the exact name. So I put on the threaded top race, obviously, that's the first thing to put on. Second, I put the spacer, then the brake cable guide and finally the locknut. I think I have the locknut tightened as much as I can get it, it looks like it will only tighten so far down and then the threads on it stop (not positive about this and will test it tonight). The problem is, the brake cable guide piece is very loose and will rotate back and forth. Have I lost a spacer? Have I lost my mind? Does anyone know what's going on here?

Attached is a before and after pick of that part of the bike. It doesn't show much, but, maybe it will help you see what's going on and at least clarify some of my weird wording. Hopefully, it's clear which is a pre- and post cleaning pic. But if not, the first is post then second pic is pre-cleaning.

Thanks
