I have a 2001 Silverado 2500 HD that I just purchased. I just noticed that the previous owner lost all the bolts to the blower motor kick plate cover. I know from another very old post that they are 7 mm bolts but I need to know their length and thread patten so I can get replacements. Anyone got any ideas? I tried looking for them on GM parts sites but kick plate cannot be the correct name for the cover since it does not show up anywhere.
