Need a dust cover for the control arm ball joint? Managed to tear mine.

I'm hoping someone may help. I'm looking for a dust seal/rubber boot for the control arm ball joint. I tore mine when replacing the top mounts. The ball joint is in great condition, so no need to replace the arm .

Has anyone got a bad control arm lying about that they could remove the boot from? Or does anyone know where I could find something which would fit?
 
separate boots are available..my local motrorist store has them you could also try ebay
