Here is another photo of the same car as above B4 restoration, it was a 69 COPO Camaro.
As a side note, note the placement of the original tune up sticker on the fan shroud.

I think the neg cable attaches to the block on all b/b in 69. I looked through my 69 AIM, and found no details of battery hookup for L78, or L34/35, for that matter, to confirm or discount that opinion. I did find a reference to grounding to the alt bracket for V8 engines in the electrical section, but I think that's for s/b only.
My correct 69 alt. bracket has 2 holes, about 1" apart. One is for the heater hose bracket, and the other is for? I guess it's possible the neg cable attached there, but I don't think so.
The alt. bracket in SSJunkie's pic is for 70 and up b/b, and has several extra holes. Is that bracket correct for any 69 b/b? Was it used on the late engines with the 3 letter CXX engine codes?

I have checked what I have left and remember what I have sold just lately in 69/70 top BBC brackets. The second hole in the 69 was for a plastic clip in the alt harness.
None of the 69 upper brackets showed any indication of a battery cable being bolted to them. The 70's however some showed the outline of the battery cable star washer and some didnot. I cannot seem to get a date however when the revision came into place. I know a august 69 cast 454 didnot have the cable on the bracket but a jan 70 cast 402 did. Not sure if this helps or not.

From the pics I have seen it appears the second hole is for the plastic alt. wiring harness connector which usually plugs into the back of the alternator?? I have not seen any pics of the negative cable being grounded to the alt. bracket so will go with the front of #2 plug/block grounding per your picture. Thanks.

Brain Fawat.....My alt wire was on that hole before I pulled the motor to replace my cam.

So did early production 70 b/b use the 69 upper alternator bracket? When did the lower bracket change from the sleeve spacer to the offset?
If early 70 b/b used the 69 stuff, I assume the extended production Camaro b/b continued to use the 69 bracket, too.
