Humm. My Mechanic recently installed the kit on my 65 Barracuda. My 5 turn steering box is now about a 4 turn. Not a huge deal other than parking is a bit more of an adventure.
The lower ball joints have the steering stops on them. I have definitely found that not all the steering stops are the same height, which changes the turning radius.
That brake kit is also a 73+ disk set up, so it does widen the track width. With the wheels further out, it’s possible you’re getting interference with your tires somewhere that’s limiting your turning.
