Which Battery is correct?

[Vette66AirCoupe]

I want to buy a bettery topper for my '66 427/390 coupe with A/C.

They offer the following:

° Delco R-59
° DC 12 Black Caps with Yellow "DELCO"
° DC 12 Yellow Caps with Yellow "DELCO"
° DC 12 Yellow Caps with Black "DELCO"

I believe the DC-12 is the correct battery but what's up with the caps? Did Delco make different color caps for different cars, amperages or years?
Which one's proper for my car?

Yes, they did, although not with any particular reason - it just happened that way with production batteries. The correct battery for a '66 is a DC-12 with black caps with "Delco" in yellow.

Thanks John!
