Ok i took a few pics of both centerlinks. Since im not sure how to post pics right in the thread youll have to click on my 69 Firebird link in my sig to see them. As you can see i took one pic of both side by side and then a seperate pic of both. As you can probably tell it looks like #1 has a bit more of an angle at the ends. Both measure 29" in length...so maybe it doesnt matter. If anyone can tell me anything from the pics please let me know. Thanks guys.
