measurements

Hey guys. JLU should be delivered in the next two weeks and as many of you who have dogs know, keeping the cargo area free of dog hair is going to be a challenge. I am going to build a pet cover that covers the floor, the back of seats and the sides. Can anyone please give me a quick measurement...

Can anyone provide the measurement for either A, B or both in the image below for a JL? B would be the top of the hitch to the bottom of the backup camera. I think all JLs are the same, but in case not, looking for a JL 4 door Rubicon hitch measurements. Thanks!
