RARE! Factory Z-Bar, Bracket & Spacer for 67-69 Big Block A body 4 Speed Cars $100 plus shipping
It uses the standard 67-76 A body ballstud and inner fender reinforcement bracket. If your car is currently (or was from the factory) a standard transmission vehicle. it will already be on the car. If you are converting from an automatic you will need to weld on the bracket.
I have the reinforcement bracket. The only ballstud I have is worn on the head but I will throw in both pieces if you need them.
Brewers has them also
