Rich, welcome to the site, and you've come to the right place if you are looking to find the original CHP equipment for your car.
If you have pics to post, we'd love to see them. You are also welcome to contribute to our tech section with any of the documentation that you have for your car. We have a documentation section located at:
http://www.specialservicemustang.net/Documentation.html
but also have a bunch of build sheets and buck tags posted up as well:

Are you planning on a full resto back to in-service condition?
