Original Battery for a '65 GS?

[Brian]

Got another one of those hard questions for the experts out there.  What was the original battery in a '65 GS?  I have been told before that it was not the same DC-12 battery that came in the regular Skylark/Special and that it was in the same size case, but was a higher Cranking Amp and had different looking caps on it. 
  Does anyone have one of these or have any info on one? 
  I talked to the people at Antique Auto battery and they don't know anything about it, but would be willing to make them if we had something to go by.

Brian,

I think the case width and length dimensions were the same, but it was a taller.
I know Loren has info on this.

Brian,
Don't know about the caps, but you are right about the battery NOT being the same as what was used in the Skylark.
