Specifically, how was the Rear Battery CABLE routed FROM THE DOOR SIL THRU THE FIREWALL for 428 SCJ Drag Pack Cars and B429. Back in the 70?s, in the Muscle Parts catalog was a kit including the cable, a rear battery tray, and installation instructions from Ford that you could order at the Ford parts counter for less than $20. I have not been able to find a reproduction of the instructions or pictures showing the routing. I have an original used rear battery cable, but the forward routing is a mystery.
Any information would be greatly appreciated.
