I was replacing my passenger regulator so I might as well replace this one too! Got these for a great price (better than anywhere else I've looked) and they went in without that much hassle whatsoever. Unlike the passenger one, which greased up the window goes up 3 times faster, this one takes some effort at the last bit to fully close (and I'm missing the cast rear stop so it should close more than needed). But it works better than before nontheless. I also stripped out the head of the screw in the old regulator and now that I have the new one I needn't worry about it :) Great buy the price!
