Idler arm gouging headpipes
You've got a:
-68-72 A-body K-member
-73-76 centerlink
-Supposed to be 73-76 A-body idler arm. It looks like that, but E/B body ones look close too.
-Should have a 73 and up large output shaft power/manual steering box.
You have a TTI headpipe but what is the part number for that TTI kit? What right side exhaust manifold do you have? Do you have a picture of it? What is the casting number on that exhaust manifold?
