Avoid this handle if you use it
Color: Black, Size: Driver side
Good Product if you don't use it, terrible product if you do use it. The plastic it's made of is too flimsy and gets worse with heat. Installed this product and it only lasted a month and a half before the metal reinforcement plate ripped off the entire plastic handle assembly.

Fitment is decent
Color: Tan, Size: Passenger side
Overall a nice replacement color matched but the fitment was a little loose even though tightened well, where the end comes toward the top of the pillar it is loose and doesn't fit flush
