Using two different brands of window visors

[NSVex]

A buddy of mine gave me his front window visors made by MOPAR, but only the front. Can anyone shed some light on the possibility of using Weathertech rear visors with the MOPAR front visors? Anyone know how close they are in person? the pictures look pretty close, but the MOPAR visors appear to stick out a little more. From what I can find, (except for buying used) I can't buy just the rear MOPAR visors. Or maybe I'm looking in the wrong place? Any advice would be appreciated!
