I had this box apart once and put a new/repro sector shaft in, but there is still quite a bit of play. As i turn the wheel you can see the sector shaft move in and out of the box before any real rotation occurs. The Tightsteer is just about all the way in...
I also found that the repro bellcrank is a poor fit. I'm going to find the old one and put it back on and then go from there...
Thanks for the input. NOS is the way to go, if available...
