As far as I'm aware, NO other quad's a-arms are a direct fit to the blaster. You can modify your frame to accept other a-arms. Blaner modified his blaster to fit YFZ suspension. That's a complicated and lengthy process which requires modifying the frame permanently.
The other option is to scrap the notion of buying other stock suspension and putting it on your and step up to aftermarket suspension. Either replacement shock absorbers (if width isn't what you're after) or new a-arms if you're trying to widen your ride.
