extended aluminum swingarm came off of an sdg. in good condition. put it on my 50 before and it fits except for the part in the back where the drum brake locks into the piece on the swingarm. all you would need to do is just get it re-mounted back about an inch and just shave it a little bit because it's a little to thick to fit in the drum mount slide. also have a few other parts for sale from the sdg, like front suspension. give me a reasonable offer for swingarm or other parts.
