Whats everyone using for a battery disconnect switch on their mopar new and old?

Sublime one said
Essentially it is 3 inches in diameter and also just a bit more than 3 inches deep. You will need a 13/16 hole for switch stud.

Is it just shy of 3”? Like 2 3/4? My old switch looks similar to the moroso one but mine is maybe 2 5/8” almost 2 3/4”
