Lots of options.
I've had good service from the Duralast batteries @ AutoZone and the brand @ North40, which are less expensive.
You can find adhesive-backed fake caps, battery top covers with Mopar logo & caps, and Mopar decals online, like Ebay.
That way you have the benefits of a modern sealed battery with a vintage appearance.
What I noticed on Group 24s is that they vary a little in physical size, so if you use a top cover, check the fit.
The Group 24 I found that fit best was the Duralast; sounds like you have a 27.
