cover bolts? mine almost look like screws on one side (rounded) and my 7mm bit is missing from my toolkit. i tried the 6.5 and 7.5 on it, it would SEEM like the 7 is the correct size. don't like going to autozone to buy single sockets in this trifiling of a size, but if they have a 6pt or 12 pt grabbing one it might be worth my while. my locks don't werk, now my blower....(when i can't open the windows)....grumble. it looks like gale had some trouble finding brushes to fit. hopefully, i won't have that problem, as i'm picking through a bucket of assorted ones. exact fit can't be a concern
