If you ever see a Mopar of 1957-1961 vintange (except Plymouth which was finless in 61). Stand directly behind it and you will notice that the fins are canted. They look straight-up from a side profile. They are not as canted that as the headlights that you mentioned (except for the 60 and 61 Chrysler/ DeSoto which are very canted). The angle on the earlier models is less. I hope that answers your question. Doug 58 Crown coupe
