Battery Orientation/Battery Cable Routing

[damnyankee36]

Did some searching but haven't found everything I need...

On my 66 Chevy I am trying to decide how to orient the battery. The best drawing I could find in the assy manual was the negative post on the fender side. Most pics I found in addition to the factory wiring diagrams say the positive is on the fender side. I don’t really trust that drawing anyway as the power feed to the horn relay shows it going through the radiator support in the wrong location.

Also, that same drawing shows the positive cable running along the bottom holes on the inner fender. But a lot of the Lambrecht truck pics show it to first go in a hole a little higher then back down to the lower holes. They also don't appear to have any straps on the negative cable.

On my truck I have two holes in the vicinity of the location of the cable strap in the Lambrecht pics. The lower hole looks like the ones in the Lambrecht pics. The upper hole in mine could have been drilled in the past.

You can’t see them in my pics but there are three holes along lower edge of the inner fender.

You can see how confused I am! Is there an accepted way to duplicate how it was originally assembled at the factory?
