all 97 TJ's had D35
98-06 all 4 cyl tj's had D35, X's and sports the D44 was optional, the Sahara and 03-06 rubi's the D44 was stock.
Personally I would never buy a Rubi, for the cost of the rubi over a wrangler X (close to 8 grand), I would rather get the X and with the money saved, buy some bolt in 60's and an atlas.
