Why would you only buy front doors for a crew?If you only bought the front doors you are screwed! With the crew you need to put the rear door hinges on the front and the front door hinges on the rear. That's just how they do it. I initially bought fronts and then realized they couldn't be installed without buying the rear doors.
The hinges are different, also the power window doors are wider/thicker than the fixed window.seems like the hinge pattern on the power window front doors are slightly different then the hinged /fixed front doors.
may have to modify.
