Will a 400ex swinger fit on a blaster???

He is probably looking for a lightweight aluminum roundhouse swingarm. The 400ex does have a 2 piece Front Pivot just like the blaster, what is the ID of the front pivot and the width from the outside to outside of the front pivot, and the size of the swingarm bolt?

If you are looking for a lightweight aluminum roundhouse swingarm then some of the older suzuki it250r can be fitted on the yamaha blaster for a good +2. They also have a 2 piece front pivot and you have to add a spacer on one side for it to fit on the blaster. BUT i dont know what years will work and i dont know about how well the shock will work..

Now i'm wondering if a 400ex swingarm will fit on the blaster like the suzuki it250r swingarm.. If the 400ex swingarm can be made to fit it would probably be cheaper and easier to find..
