My service CD calls for adjusting the engine stop at what appears to be the rear cross member using a gauge #201 589 04 23 00 (02). I haven't actually been under there for this but know I have one faulty hydraulic mount and figured I'd go though the whole procedure. Thanks for your reply. I'm sure this will all reveal itself when I get to it.
