Question about fit of 68 Dart Exhaust tips

Well, my exhaust system install is done.
I couldn't use the stock type hangers for the tips. My tips are for a 71 and i'm putting them on a 68. The hanger on my tips is farther forward than on 68 tips. (or so i've been told.)
Anyway I went with a different type hanger. The tips extend about 1-1/2" past the bottom edge of the bumper, but they are also about 1" lower than they should be.
I'm not worried about correctness or anything. They are mounted nicely and I like the way they look. Heres a pic of how it came out.
