This is a complete bolt in kit that uses a modern power booster and dual circuit master cylinder mounted to the firewall using the bolt holes for the factory air box. It includes a new brake pedal that swings from a higher location (looks like it could be original too). A modern GM booster and master cylinder give a significantly improved braking feel and power while adding safety through the dual circuit system. 
 
This can be used with factory drums, disc/ drum or disc/ disc. Let me know what brakes you have at check out and I will send the correct proportioning valve. 
 
It will have the pedal feel of a modern car- minimal effort required with a positive and firm feel. No more soft or sloppy pedal! 
 
Installation is fairly straightforward- no cutting of the firewall is required. Takes about 2 hours to install. You have to remove the driver side air box, master cylinder, original bake pedal, and then this kit bolts in.
