The GM #3831586 is the rear spring end bolt cushion applicable to 1963-82 Corvettes.

The GM #3788637 is the UPPER differential "snubber" mount (cushion) applicable to 1963-79 Corvettes.

Both parts remain available from GM to this very day, 50 years after they were first released.

Once-upon-a-time you could buy that unit of parts (i.e. bolt, nut, cushions, inner and outer retainers) from GM under GM #14029851.
