I need to get my truck posted then I guess,it would answer this question since the person that replaced the rusty front didn't know they are different it is a quad cab long bed with regular cab and club cab style doors the back of the rear doors on a quad cab is squared off so it takes a different door,since the bottom corner of the rear of the front door on the regular cab or club cab is rounded..so even the guy I got the truck from is like the corners of the doors at the back are rusted off,I'm like nope wrong doors.
