What was found

(CAN) DURING ENGINE MOUNT REPLACEMENT IT WAS NOTICED THAT THE NEW MOUNTS WERE MANUFACTURED WITH THE BEVEL ON THE WRONG SIDE OF THE METAL PART OF THE CORE (R20700-11). THE CORE IS MADE OF RUBBER SANDWICHED BETWEEN TWO PIECES OF METAL. THE BEVEL IS THERE TO ALLOW THE INSERTION OF THE HAT BUSHING, THESE PARTS ARE ASSEMBLED WITH AN INTERFERENCE FIT, WITHOUT THE BEVEL IT IS VERY DIFFICULT/ IMPOSSIBLE TO INSERT THE BUSHING. STOCK WAS CHECK AND THREE MORE KITS WERE FOUND IN THE SAME CONDITION. THE PARTS WERE REJECTED.
