I had FirmFeel's beefy tie-rod assemblies put on my '67 300 when I had the front suspension upgraded in 2008. Well worth the coin imo.
Firmfeel Mopar Suspension and Steering
I've got a Stage 1 unit and the 1.12" bars in my 300, money well spent, but I should have rebuilt the original swaybar bushings and thrown a rear bar on it.
Bilsteins would be a nice upgrade over the KYB's too
