Trailing arm bushings

[JIME]

I know this topic has been covered several times but after reading throught the specs on energy suspension's website I have some questions. To do the replacement of the bushings will all I need is the 2 piece split poly bushing, sleeve, and new bolt per bushing? I was looking through enegy suspension's website reading thier specs on their busings trying to find a more economical alternative to the bushing kit. The specs talks about the diameter of the outer tubing. In the pathfinder's application would the outer tubing be the tubing on the actual trailing arm? Picture attached of spec picture.

 

Does anyone happen to know the true specs of the trailing arms on the 99.5 pathfinder? I just need to know the inside diamter of the outer tubing. Or the outer diameter of the sleeve.
