The Catholic Church is the same church, before and after Vatican II. The traditionalist schismatics embrace the modernist heresy that it is a new Church after Vatican II. Like the modernists, they are wrong.

If I get the sense of your post correctly, Vatican II didnot create two successor churches; the Traditional Catholic Church representing the Church before Vatican II and the Modern Catholic Church representing the Church that arose from Vatican II. Before, during and after, there was/is a single Catholic Church.
