I went through the rattle problem with a 91 Seville. It has the same basic set up as the Allante. After going through new bushings and pins, the rattle was still there. It wound up being excessive clearance between the new pads and the bracket they hang in. It was a combination of the new pads being shorter side to side and the bracket being worn where the pads would hang. Shims solved the problem and the rattle never came back.
