While I was under my dash, I noticed some of the plastic pieces that are a rectangular shape are broken or missing. There are three of them and they allow the steering column to mount up to the dash frame and the cowl area on the car. They are off white in color and are where the studs go through with that large serrated type washer that holds it up under the dash.

Any leads would be greatly appreciated.

I believe these are what you need. Available from a few different vendors as well.

Richard Eberg of Mopar Action had them on his ebay store and he in in NY close to you. At least he used to have them, I think he still does.

Thanks for the info. I found them now Duster340. Guess I just wasn't using the right "key words".
