As evidenced by my garage, I hate to throw away anything that someone may need, especially if it is as hard to find as these may be.  Picked these up with a lot and they were tagged together with the tag that says 1960 Chrysler.  That is all that I know about them.  They look like they may be dust covers for something, the rubber is pliable and one on the right side may never have been used.  If there is a '60 Chrysler guy who can help ID these, message me.
