Greetings, I opened up my doors to try and address the window rattles and found the "Lower Door Window Bumper" (http://www.thezstore.com/page/TZS/PROD/30-2357) just laying loose at the bottom of both doors. I can't figure out where it is supposed to be attached. The factory service manual does not even mention this piece, much less show it. The one place that looked like it would be a logical fit was a metal pedestal of sorts near the rear of the door, that has a hole in the top that looks just about right for the clip, but when I tried it there and rolled the window down it wasn't even close to aligning with the "channel" that's in the bumper. Unless the channel isn't for nesting with the window? Is the bumper supposed to be aligned "side to side" instead of "front to back" (which was my assumption)? Any help is much appreciated, and pictures are worth a thousand words! Thanks in advance. 1973 240Z, build date 9/1973.
