I just received mine- lousy directions, actually none at all. They provide 4 small rubber dots to stick somewhere between the plexi and the roll bars. On the R-171, the roll bar rears are not flush and the dots won't stick to the curved bars (even using alcohol). Has anyone else bought this product and used it/the dots? Seems like they aren't really necessary. This is my first post, just got a used 2006 350 and pretty excited.
