I am installing rack & pinion from uni steer. They sent me the wrong bearing for the steering shaft, they sent a 1" and mine is alot smaller, about 3/4". Does any one know if it is 3/4" or a bit thicker, can't find my mic., one of the only times I need it!! I have the swing away tilt column with rag joint, might be an early production car.Thanks for the help.
