OK Guys I have a lot of questions today. well I started a 4.0 swap into my 87. in doing this swap I changed the gauge cluster from a 04 not thinking of the fact that the gauge runns off the rear axle vvs sensor. but I alrady bought matching 9inch and d44ttb for this project. So I was wondering if anybody has ever changed the tone ring on to a 9". the guys over at desert ranger swap 9" into the prerunners and do the tone ring change over but I cant get a responce from them. thank guys.
