I got the new grills on with out taking the door off. I tried to put them on before without taking the door off before but I could not push the retainer clips on with my fingers. So I ended up taking a couple of nuts taping them together and put some double sided tape on the end to hold the retainers. Then I was able to push the retainer clips on with the nuts. The new grills look better then the old ones with holes and the car is back in tiptop shape.
