I am confused about 1973 Mach 1 stripes. Almost everything I read says the side stirpes changed in 1973. But I have several books that show the higher full length stripe on a '73 as well. Then I surf the net and see both the lower 3/4 length stripe on some and the higher longer on others. The rear stripe change from 72 to 73 seems to be consistent, but not the side. Can someone clear this up? Thanks.
