I need to reattach the acclerator cable to the spedometer, as well as a good bit of wiring, I've taken out all the screws i can find (and double checked my mechanic's manual) on the dash face, and the entire plastic piece is held in soley by the radio.... and the leather dash cap. the radio dictates that the dash face be pulled out parallel to it, but the lip of the dash cap stops the plastic from being pulled out, and vice versa. the dash face is intact and so is the dash pad, is there any way to remove it without just prying it out from under the leather cap and hoping that 35yr old plastic won't snap?
