hi folks, my driver's door (with manual window) has never sounded particularly decisive on closing. i found that the spot weld had gone on the window channel support bracket and replaced it with two little allen bolts. that's better, but it still sounds like of rattly, even with a new seal. i don't see any loose bolts, so i'm asking here: what else should i look for in the door to tighten or bond in some fashion?
