Just installed BBK Shorty Headers on my 07 GT. I had to remove the steering shaft in order to complete the installation. Once the installation was complete and the steering shaft was re-installed, I now have slack in the steering (at the steering wheel) that was not there prior to the removal of the shaft. I have removed the shaft once again and re-installed it (making sure that everything was tight) and I still have the slack in the steering wheel. Any suggestions on what I can do to get the slack out of the steering wheel would be appreciated.
