When doing a top shift conversion on a forward shift T case, you will need a block off plate to block off the old (unused) hole in the transmission that the forward shift shifter was in. In addition to that you will also need a new top shifting shifter to shift the new T case, or even a twin stick if you are going to run duals with a 4.7 gear set. That is why Kit C is a great value and the most complete kit for the guy who is going to go all the way with duals, 4.7's and a twin stick.
