This is an adapter mount that bolts to the NV3550 / AX15 transmission and allows you to retain the stock Peugeot muffler support and rubber mount. This plate offsets the Peugeot rubber mount forward from the NV3550 / AX15 mount holes to line the rubber mount with the stock slots in the crossmember. The stock slots in the crossmember support may need to be elongated slightly.
