Congratulations.

By the way I'm no expert on 72 T but recall from inspecting a friend's calendar 71 model year 72 S the earlier front S spoilers that model year were fibreglass -- before they changed to steel. Think date and or chassis number of that change was referenced in the workshop manual and in a thread here. Your prerogative to change bumper spoiler but mention this in case it affects your decision to change it pre paint.
