As an aside, I should say that it is interesting to note the difference here between ABLs stance – that Vatican II must be read in the light of Tradition – with the current SSPX stance - Vatican II cannot be read in the light of Tradition.

I didn't realize Archbishop Lefebvre was an hermeneutic of continuity guy. Good on him, if that's true. I wonder if anyone has a citation from Lefebvre on this point.

I wonder if anyone has a citation from Lefebvre on this point.

A Google search turned this up:
An Interview with Archbishop Lefebvre
Interview granted by Mgr. Lefebvre to Dr. Eric M. de Saventhem

From near the middle of the page:

If I were asked to declare my adherence to the conciliar texts "read in the light of tradition and integrated with the dogmatic formulations previously laid down by the Magisterium of the Church," I would sign without hesitation.

It may not be a definitive citation, but there were many other search results.
