Hey scott. Am unsure what knocking noise you are hearing but that cant be good. Im unsure about manuals so maybe someone can chime in. Also what parts are you looking for? Some things just need to painted to match
Wow, thats quite an intro! Stang looks like it held up well over the years. Appreciate the read along with the pics, especially the one with the doggo!
