It's a little bigger than the original, so if you want it to seat on your original pad, it will overhang a little. A smaller version will fit on that better, but give you a little less CCA.

I bought my most recent battery for my 56 Dodge from Costco in 2018. Last year I bought a fake "tar topper" for it. Looks reasonably authentic. The positive post is at the rear, closest to the fender mounted starter solenoid.
