I almost did go with a D-60 but cost, gear selection and EASE of changing them had me go with a 9". People get too tripped up on the subject when it comes to rear swaps. At the track you will see at least 95% of the serious racers are running a Ford 9" no matter what brand of car it is. There is a reason for this. They are less $$ easier to find parts for and are hella strong. No getting around it.
