I removed the full length metal sleeve that nissan pressed in and now know how foolish that was.
This image shows you what I want to make and the dimensions that should work.

I remember seeing some fabricators here selling CNC machined items. Can someone point me to one of these guys or do you know of anyone who can make this.
I live in Laurel, MD, 20707.
Does anyone know of a shop near here that can accommodate this request?
