Hello, I have a 1978 Mustang. I lost the keys and have a new replacement ignition lock. I have the shop manual, but it says i need to turn the lock to the "On" position to take the old lock out. Problem is i dont have the key to do that? ??? there has to be a way to replace it without the key? Please help. I tried calling ford to have them cut me a new key, but they told me it is too old. Locksmith was too expensive so i figured i would replace the the whol lock.
