Aftermarket rubber have no metal bushing inserts.
About two years ago, I bought the
front motor mount rubber/assembly with the metal tubes/bushings in the rubber, around the middle two holes. These codes are on the rubber: 112 over 2007 (maybe the year it was molded?).
I do not recall if I bought them from Jim Carter, Classic Parts, or Chevs of the 40s (I have two mounts with the tubes/bushings).
I had to call and ask the venders, to be sure the metal tubes/bushings were in the rubber mount.
