Depends on battery option and engine option.

I wondered why you asked so I did some research.

Maybe not everyone is aware, 6 cylinder and Z/28s used a reverse polarity battery + term on the left. No matter which battery or cable configuration was used, the - ground wire is terminated on the fender brace.

However for '68, reverse polarity batteries terminated on the core support. I assume you are wondering if this continued into early '69 production. The '69 AIM shows the fender brace termination but Rev 5 dated 3-3-69 states "NEG GROUND DWG REVISED." Doesn't state what was revised.

The late John Z once advised not placing much stock in the dates in the AIM. I checked the January '69 Hot Rod magazine road test of a '69 Z/28. Early Van Nuys car built on or about 10/1/68. Pic shows a reverse polarity battery, ground wire terminated on the fender brace.

... sounds like you could just find your favorite location (don't drill any new holes) and no one would ever prove you wrong... :)

This is the hole for the terminal ground on my X77. Unmolested tag and "A" dated tank visible, support was removed intact many, many years back (too long ago, as a matter of fact).

 JMHO... I have always said with no authority, that I thought it should be stated as "Reverse Post", not "Reverse Polarity". Rev Pol would mean you have power coming out of the ground side post. Because you are reversing the polarity. Reverse post would mean the posts switch positions in the battery and the electrons follow the post to the other side. Just an observation I guess.
As far as ground straps... all of my cars that are original '68 Z/28's have the ground strap attached to the radiator support with an interior exterior tooth lock washer. I have never seen an original '68 Z/28 with the ground strap on the fender. Out of 7,199 it exists ?? ... Danny

Something I thought was very cool on one of my cars... A factory arrow marking on the core support heading towards the radiator. I wondered if that was to show this car is a Z/28 and needs the ground strap on the core? Anybody know?   Danny

Danny:   How do you know that is a factory marking? (the long big arrow).... I'd be a skeptic of that...
