Need inside dimensions for Group 24 battery topper.

[GMP440]

I want to buy a red cap battery topper for my flat top Group 24 battery.
I need the inside measurements ; length, width, height and measurements of the terminal holes from center to center, distance of holes from the sides.
  Maybe someone with a Group 24 topper can give these measurements.  Thanks.  George

Just go to the local parts house and measure a standard group 24 battery. That is the only style they fit on to my knowledge. Should give you the measurements you are looking for. Or email/call batterytoppers.com
