64 dart brake/suspension upgrade
I went with all Mopar BBP parts on my '64 Valiant convertible and I can't imagine anyone wanting or needing a better setup on a driver. I was able to find almost all US made suspension and brake parts from Rock Auto and upgraded the torsion bars and steering box with Firm Feel parts. The only thing I have not yet done is add a anti-sway bar.
It's like driving a new car and I can buy replacement parts without having to go back to a manufacturer who might be out of business next month.
