The cone on the right side of my rear wheel is pitted. I’d like to replace it. However, I’m afraid to screw up the alignment of the lock nuts if I take those off.
I want to measure the cone to see whether I can find the right replacement. Do you have any tips?
I’m thinking maybe take the cassette off, reinstall and tighten the axle before taking off the drive side nuts and cone? (Leaving the non-drive side nuts and cons on) That way the spacing shouldn’t move too much?
Bonus question: should I even bother finding the exact type of cone? It’s from a mid 90s mtb. What are my other options?

Step one: inspect the mating cup. Good chance it’s pitted too, in which case the wheel is trash
I had that problem few times. Replace bot cup and cone. Replacing one will lead to other being destroyed in short order because it’s weak and worn already even if you can’t see it. Cost of replacement will likely be the same as used replacement wheel so there is this to consider.
The threads on that axle look jacked but maybe it doesn’t matter if you can unthread that come/replace it
That’s not wear, it’s from corrosion. Water beading where the dry bearing rests against the cone and didn’t get moved for a long time.
Replacing the cone would be the best option, but in my experience liberal amounts of grease and some fine tuning with the preload will result in hubs that run just fine. I have seen much much worse, your bike will drive ok with this.
