Diff supports for mk1/mk2 mx5. These have had the rubber removed from them in order to fit into polybush rear diff mounts. They have also been wire wheeled and painted black to prevent rust.
I purchaseds 2 mountings to replace the old ones of my 29 years old Miata NA. The rubber was separated from the metal sheet of the left side one, so I decided to replace both.
The chnage is very easy if you jack th emiata on the differential because it rizes and holds the diff on place. Put also two jack stands on both side of the car.
