I just picked up a used woods 5' brush hog and it needs a pin that holds the PTO on, how do you install one of the spring type pins and where do you get them? Also, the sides are dented in a little and it looks like they unbolt, do they sell new sides or how do you straighten them or fix them? Other than that, it's very solid with no cracks or breakage. The sides aren't terrible, I'd just like to have everything looking nice when I start to use it. Thanks.
