Thank you very much Bill! The teeth when I just looked are pretty pointy and look like it has been barely used. When I physically push back the handle spring it seems to lock in correctly, then if I push the trigger lever shaft to the middle of the handle shaftover towards the passanger side it locks in tightly. I have it rigged up to work for now, but I thought there might be a guideline to go by or a worn out part to by? Trying to restore this hansome truck. Thanks for your help!
