The topper measures 7" X 10 1/2" and is well made IMO. Not cheap or cheezy at all :poke::D
A minor (IMO) modification was needed on the battery hold-down as it was just a bit too narrow to fit the topper. Ended up cutting off the vertical side of 1 end of the hold-down nearest the inner fender. Not noticeable when installed...
Here's the finished product. Hope you agree it adds a Mopar touch to the engine bay for a fraction of the cost of the reproduction batteries. In addition, when the battery wears out, you can move the topper on to the next battery.
