Hello, I had my rear belt sprocket pop four of its six nuts off. I was wondering if I would have to buy a new rear wheel. When I line up the sprocket over the holes, it looks like it was welded on. It did a real number on it. I own a 06 Blast, found a 01 rear that was reasonably priced and was curious if that would work, or would I have to get a 06 rear. Thanks in advance for any info.
