YES.. SBC installed these for me today.. (glad I live in the valley) and yes it is overwhelming to pull your window out of the door.. but I figured "Hey, it wasn't attached to anything anyway.. ya remove the old tabs.. hot glue the new bracket on.. (make sure the window is lubed when it comes out and it should go right back in lickety-split.
for those of you having troubles.. picture 2 plastic tabs holding on to a 10-lb window.. then picture a metal brace 7 inches wide holding up the same weight.. It was money well spent as far as I am concerned..
Thanks again Tim.. you helped me out alot.... even helped the tilt go away.. but I am sure that the lubing will still need to be done regularly to keep'em that way..
