73 US front bumperettes (and rear bumperettes for that matter with rubber spacers) are the same as all US thru 73 and all Euro. I am referring to the chromed steel part of the bumperette, the rubber is the only difference in the 73 US front bumperette, and if you dislike the "upside down" look of the 73 as much as I do you can replace the rubber with an earlier year right-side up piece quite easily.
I didn't get a good look for rust, but I didn't see anything. She did mention there was a rust on the floor but she repaired it. I'd say the interior is good, there are some areas on backseat is very dry and started to crack. I would say the seats can use some refreshing. The paint is decent, there are some paint corrections. I'd say its 10-footer car. I hope this helps!
