Oh thats interesting, is your paint original or has yours been re-painted once? On the spitters I'm not entirely sure, see my car had to have the exhaust replaced some time ago. It now has complete Aluminized mandrel bent exhaust, but it isn't positioned correctly. My splitters are at a slight angle yes but only about 3/4" of them are showing. I think that the splitters are suppose to be about 2.5-3" long total, but only about 2.25" showing and angled out.
These look correct to me:
I've been looking around now at '75 T/A's cause you had me curious about the decal... I'm not sure they were there or not. I've seen about 12 photos of 75's and only 2 have them. Of course its hard to say if they were placed there during a re-paint or not? I'm going to see if I can find a decal placement sheet for the '75
