Battery Cable – Square or Round?

Own a '67 small-block cuda. Gonna order a reproduction negative battery at yearone.com and it shows two options: square head cable or round head cable.

Long ago I replaced my cable with an ugly aftermarket one and I threw out my original cable. Which one's the original style...square or round?

Also, yearone.com is running a 20% off sale today. Just enter this code: RACE10
