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?

Run that battery ground directly to the block.
Run the small wire to core support.
Run a ground from a drivers valve cover bolt to the frame.
Run a ground from a passengers valve cover bolt to the firewall.

Hmmm, you seem to be answering my other post about where to attach the small ground wire terminal.

Thanks but since I'm trying to get it as close as feasible to the factory specs, that's why you see the neg battery cable being attached to the AC compressor bracket. I know the smaller ground wire needs to go to the sheet metal somewhere but I haven't found a previously placed screw hole anywhere. That's why I am wondering if the wire's ring terminal might be sharing one of the 5/16" sheet metal screws.

I haven't got to the rest of the ground straps but I think I have that covered.
