From a 1966 Mustang. The back of the switch broke off so i need to change the whole assy. I read the you turn the switch with the key to acc and insert paper clip and turn back to off and it should pop out. Will i have tried this a 100 times and it still will not come out. I can feel the spring compress as i insert the pin in the hole. Any ideas. I in the middle of changing the dash wiring harness out and hope to make a car show this weekend. This is my brother's Mustang.

Thanks

Steve
