Renewing the fasteners in the assembly at the same time you are replacing this MUFFLER PLATE will make fitting much easier - interfacing new parts with old nuts, bolts and washers can lead to problems and does not look very nice any way!
Please make sure that the part numbers you order are compatible with your model.
Mixing old parts with new is not advisable - nor does it look very nice!
It would not be possible to refinish the old item for this price!
