Welcome to the Team Jason!
I have heard (I have no direct knowledge myself) that the 1969 and '70 model years as well as the 1968 year had a lot of one year only modifications of standard parts.
What is wrong with yours? Can it be repaired with a small fiberglass parts repair kit and some plastic filler designed for working with fiberglass. If it is broken into a two or three pieces you might be able to glue it back together and patch it up. If it is totally missing you will need to find a parts car to make a donation.
