Like I said above I did do the search but couldnt find what exactly a tripod style cv is. I think it is the inner part of the cv that goes into the diff am I right? It looks like the is 3 notches taken out of the larger part? The reason why I ask is because I ran accross a thread that says you have to run a tripod style on an ADD truck. Well Im a bit concerned because I just put 2 new cvs in and they are perfectly round on the large end and they work well.
