On my rear window, I noticed there was a hole in my window where a plug should be but is not. A buddy of mine has the same Jeep that had a plug. I thought the hole was supposed to be there until my back floor was soaked in my TJ. Does anyone know where I could find that plug? I rigged it up just to get by! Also, how do you refill the back windshield wiper fluid? Thought it would be connected with the front but I guess not! Thanks!!!!
