what rear ends will fit??

There are errors in that chart. In one place is states that 67-70 Mustangs are 59.25 (correct) but in another it says that Comets, Mustangs,etc.. are 59.25 from 67-71 (incorrect). There are three widths: 65-66, 67-70, and 71-73. In yet another place it states the correct info for 71-73. Judging by this, I wouldn't trust this chart.
