This is the first set of mounts since I got the car at 109K. Cant say for certain but believe what I removed was OE. Both old mounts have a MB logo and what appears to be a 98' date stamp (mine was produced in 98). Neither MBDOC or Gilly felt the W210 was an exceptional mount eater contrary to what I found posted in threads from 3-4 years ago.
When lifting engine be careful not to lift too high, would be a shame to split a good mount by using too much force.
FYI - I outlined my expiriences R&R'ing the mounts in this post.
