Cars made in the late 70s are likely to have rotted out steel inserts anyway, which are not supplied with urethane bushings.
If you are interested in buying these OEM parts new to make your car feel like new again, show your interest buy responding to this post.
This is just to let you know that this is an early stage of the process, a necessary first step, but no, they are not being made ,,, yet.
