Correct power antenna 1970

I’m looking for information on the correct power antenna for a 911 E from 1970. I’ve checked the work shop manual and its looks like its a Hirschman 6000 D 35, but I’m not sure. Can anyone supply information on the correct power antenna? Any photos of original installations?
Thanks

Bumping this for any 70 owners with a power antenna who can share a pic or model number of their antenna.

Thanks!
