here are two links to some threads which describe the removal of the vents to the right and left of the instrument cluster, which is another way of getting the cluster out. I think it is better because there is no chance whatsoever of scraping or damaging the cluster, and you don't have to buy or make any tools. It can easily be grabbed and pulled out with the vents removed.
