Anyone know where i can find seat covers of the triple front seat option. not a bench. I cannot seem to find them anywhere , or they just don't make them yet. I have a 2016 pro master with 3 front seats. the driver seat is separate and moveable that one is no problem. but the other 2 are actually 1 seat and non moveable. this is the seats I'm having an issue finding a cover for , any ideas ?
