I’m a german citizen since birth, even though I was born abroad and only came to germany for the first time when I was 20 years old in 2012. I’ve stayed, studied and worked in germany since then. My country of birth has numeral citizens of german origin, so this topic has and had quite some relevance for me. So I can tell you from personal experience that you have nothing to worry about. Neither I nor any of those I know in a similar situation who came to germany after me in the subsequent years (after the 2011 abolishment of consription) were ever summoned to a military medical inspection.
While the other answers raise some interesting points, most of them are more of a historical or theoretical relevance. The thing that really matters in your situation is rather more simple:
Germany has abolished conscription in 2011 for all intents and purposes that might matter to you.
It’s true that the constitution still has the language in there, but reinstating the actual practice would be a major political decision taking at least weeks to months, not something that could suddenly happen next Tuesday. This applies regardless of your past situation: There just isn’t any infrastructure for drafting people; even the law regulating the details of conscription now states that it isn’t in effect unless Germany is under attack.
I also wouldn’t worry much about any kinds of fines for dodging conscription; Germany has statutes of limitations even for almost all crimes (short of murder) that would long have expired since the 70s. In case you were actually already sentenced or asked to pay any large fine back then you might want to speak to a lawyer though.

To add to Hilmar’s answer:
I found this snippet from 2005: https://www.yumpu.com/de/document/read/32644844/wer-ist-wehrpflichtig-sind-auch-deutsche-im-ausland-vereinbiz
This states that the draft is "suspended" if you live permanently abroad (and you or your parents make all their money abroad). According to this document, you have done nothing illegal since you weren’t subject to the draft. The draft would resume when you return to Germany, but since it’s been discontinued that’s a moot point.
In any case you are way to old to serve (no offense). Retirement age for non-officers is 55. If you want to make sure you can just contact your local consulate or embassy. They are often quite helpful.
DISCLAIMER: I’m not a lawyer and don’t pretend to be one. If in doubt, get real legal advice from a certified professional.
