Did you ever check your track bar? Most death wobble in TJs is from the track bar. A tiny amount of play in the track bar will cause death wobble. Death wobble is scary and if this is mild and doesn't make you crap your pants it is probably not death wobble
If it is a regular wobble at specific speeds I would check for a balanced driveshaft next since you already checked tire balance.
If they are chevy 1-ton tie rod ends then any chevy 1-ton end will work. The links that were posted in your last thread are probably the ones you need. If you can't make that work, then go to Autozone. Say I need steering tie rod ends for a 1986 chevy 3500 SRW. DO NOT ask for ball joints. That will be the part that connects knuckles together and not the steering parts.
You could always pull your tie rod and take it in with you and compare.
