the switch over was during the 1971 model year;
Early cars had the "square", late cars had the "kidney".

What may have confused some is the GM replacement quarters were the "current" version - they didn't care about little details like this.
My car had replacement GM quarters hung on it some time before late 1985;
The entire door jamb area was left on the replacement passenger side quarter, while the drivers side door jamb was left (the quarter was brazed on just inside the lip into the jamb).

Because I haven't heard from anyone, I assumed that I was more or less going to have to recreate the correct indentation - I may salvage a section of my original drivers side door jamb for this;
That section isn't as bad as I previously thought - it was just mostly covered up.
But a replacement solid jamb would be much more desirable to me.
