Tony, thanks for asking. You need to make sure there is not a project attached to the profile, and you need to follow style guides.
I am going to give you a link to follow that will help you on Pre-1700 profiles.
You need to pre-certify yourself to work on Pre-1700 profiles and on the bottom of this link, you will find that information.
If you have any other questions, this is a great place to ask them.
Hope you had a great weekend.
