Which one
Normally I wouldn't fret about the track width for a reasonable lift, but the narrow track axles are just TOO narrow. For 2.5" of lift and 33s, I wouldn't really worry about it. Maybe an inch or so if it makes you feel better. The Wranglers have wide axles, that's why they come with such large backspacing on the factory rims.
If a Wrangler had the exact same size wheels and tires as your CJ, the Wrangler would have a 7" wider track width. A wide track CJ would be about 3" wider. That's what most people do with the narrow tracks when they run spacers......go with a 1.5" spacer and it makes it into a widetrack. It looks alot better and is more stable
Front axle widths: NT CJ= 53"+/-
WT CJ= 56"
YJ/TJ= 60"
NT Wagoneer= 58.5"
WT Wagoneer= 63"(?)
Scout II= 58"
Early Bronco= 60"(?)
Fullsizes= About 67"
Considering the extra weight and height that a similarly equipped narrow track Wagoneer would have to run the same size tires as you, your CJ would probably be more stable even at factory width.
