i have a 1991 extended cab ranger and i was wondering whats the size of the hump in the back of the cab on the floor. i tried measureing it but couldnt get a good outcome, they were all different numbers, thanks ahead of time.

 

So, what are you trying to do, make a speaker box. it's kind of hard to measure, just make a template out of cardboard, then you can get the fit you want without screwing up a piece of wood.
