Dave, I'd recommend that you not yank any harder and remove the screws that secure under dash panel in the driver's footwell. With a light, locate the threaded cable to the speedo and if necessary, remove the pressure fitted a/c ducting to the side vent to gain better access. Disconnect the speedo cable before pulling the custer to eliminate the risk of a jumpy needle at low speed due to stretching. Once you've disconnected the speedo cable, you can PUSH the cluster out from the back without the use of any hooks.
