Anyone familiar with an A/C System on an A-Body? I’m trying to understand where the blower motor ground eyelet is attached to on the firewall or inner fender. Specially a 1970 340 Dart. Photos of engine compartments or details would be greatly appreciated.

I can't talk on A bodies, but 71/74 B bodies uses one of the A/C-heater box studs with the nut to the firewall. I think the eyelet terminal get somehow a star washer shape to cut into the paint? can't recall.

On my 68 I seem to recall the ground being screwed to the side kickpanel metal. Been a while since installing, but having flashbacks.

Yah, my 68 non A/C blower motor attaches behind the PS kick panel. A/C cars might be different.

Correct but I don't have a picture and pretty sure A bodies are the same as well

Thank you for the feedback. I was trying to find some old pics before the 70 Dart was torn down, Here is a pic that I initially thought it went over to the wiper motor stud. But the wire that was spliced may be the blower motor wire, it's difficult to tell.

Unfortunately, I do not have a photo depicting the right side of the engine compartment (up close). I only have the pic from the online ad, but it's too difficult to make out the actual routing with all the pluming going on.

Motor is in same location for both, so I am guessing ground is same spot. They may choose that location to move further from radio or something (AM noise).

I would take the harness and lay it out to see how it fits. I am also remembering it went under the carpet to get to the side kick panel. Wasn't what I expected, but I saved old carpet and could see where the wire was laying and imprinted on back.
