Bolt in application designed specifically for 67-72 trucks. System costs are $695, which includes a brand new '06 production heavy duty hydraulic brake assist unit, the CNC machined T-6 billet direct fit firewall mounting plate, adjustable height brake pedal rod design, and the genuine Aeroquip braided stainless AN-6 lineset materials, ready for a direct bolt in.
We can set these assist units up for most conventional 2 bolt design master cylinders by request, though our direct preference is as pictured - the stock master cylinder. Not yet on the website, but will soon be there. For now, please call to place your order.
