I don't really know what the exact part no. is since the old one was replaced by a dealer who is no longer in business. I really don't know who sells Monaco in my area. The Monaco parts folks aren't sure what was used on the older coaches. I have run into this before when trying to get parts. Hopefully, someone on the Forum will have a Part No. that can be crossed if not available. As you may know, Monaco has now changed hands twice. So, finding out exact Part No.(s) is going to be a chore. Thanks for your help.
