Jack's Comments:

Exact reproduction of the firewall to engine cylinder head ground cable hardware. Bolt is for the back of the passenger side cylinder head and the screw is for the firewall. Correct for both the C8ZB-14303-A and C8WB-14303-A ground cables.

Concours Notes:
1) Scroll down to see this ground cable hardware on Bob Perkins 156 mile 1969 351W Mach 1. As you can tell from the pictures it was installed after the firewall sound deadener was sprayed on.
2) We have seen the screw with and without a D on the head on original unrestored survivor cars.
