Thanks for the information, but the drawing does not look like the one I have. My tilt portion is before the ignition switch. I have the steering wheel off but there is a part of the tilt wheel assembly that has to come off to get to the ignition.

ok I will opt out and see if another expert can help.Thanks

HelloCustomer

If you have the steering wheel off you are probably looking at the lock plate.You will need a lock plate depresser to remove this part.It screws onto the steering shaft & depresses the plate(spring loaded) just enough to get access to the snap ring in the center.

Customer: replied 6 years ago.
Hi, Mine does not have a lock plate, I took the turn signal assembly off and what I am looking at is the stub the steering wheel bolts to, the tilt stub is mounted in a bearing which is mounted in a plate about 4" square. When you tilt the wheel this whole plate moves. I need to get this plate off to get to the ignition.Thanks
Expert:  John replied 6 years ago.
Can you send me a picture on "you tube".I am not exactly what part you are refering to.
Customer: replied 6 years ago.
Sorry no camera.
Customer: replied 6 years ago.
If it helps at the bottom right corner of the square plate is a round hole with a spring that tilts the plate.
Expert:  John replied 6 years ago.
I will back out & letCustomerhelp you.Have a nice day.
