'70 Z 28 correct battery, side or top mount post?

[Jacsey 70Z]

The different size pos. and neg was to keep people from getting the cables crossed, with the new side post batteries. Didn't take long to go the same size for both. This explains why the negitive end of my original cable was cut off and a univeral clamp on type was added. the first time the battery was changed they had to.
The negitive cable is a reproduction, but it's the exact cable and length and number as the original.
