I don't believe it will fit out right? Although the Wrangler and CJ7 tubs are similar, the internal supports would be in different locations. Although anything is possible with enough Fabing. Also consider that a CJ's tailgate opens downward and the Wrangler is from left to right.
The track bar I'm sure about either? The CJ's did not use track bars and have no provisions for them. Also the axle width are different.
