Tremec TKX first cuts

Hi there. Thanks all for the posts on this thread. I am about to do the same on a 67 auto Dart. The car will be daily driven, canyon carving and a little road course. Top bracing will be seriously considered!

To those who fitted theirs, will the USCT driveshaft loop that bolts onto the cross member still work? I want to keep mine and reuse it for the TKX.
