Query: Don't waste your money!

Installing it took about 45 minutes, but the plastic piece that rides in the door track popped off where it was supposed to be bonded to metal slider. The metal slider screws through the window into an anchor like structure in the form of a circle . The original is a 2 piece design. This one is a 3 piece design. I should have bought an OEM piece. I hope this saves you the time I wasted. To fix it I had to epoxy the two pieces together.
