Congrats! I'm still running the stock 10x.2.5" drums. They're larger then the stock D35 brakes. I forget if the ZJ used D44 axle flange pattern or a D35 pattern. Although, you should probably find or make a new mounting bracket. If they did work, you'd need to press off the bearings on the axle shafts and use the ZJ's retainer flange so the thickness is correct.
