LOL.... You will love it dude, I wanted to try my spool setup but ended up staying with the diff, because of the time issue. I feel that the spool with some setup changes to go along with it will be the ticket here. I let several guys here try it out and they were all very impressed. The only thing that some said they would like to see is a small hole on the front and rear to allow access to adjust your diffs with the body on.
I will call you Monday...
