You should look for a full face dust mask that will fit in the glove box while your at it!   I absolutely love the Rangers,  but they really are a dusty ride once you put a windshield on them.  The dust absolutely rolls in the cab on them on a dry dusty field or roads.  That is sometimes the price you have to pay for the times when it's cold windy and rainy though, then it's a must.   Some have said that you need a back on the cab if you do the front windshield.
