It is one problem that I never managed to solve on my '87 5KT. I replaced
both the engine and transmission mounts and the engine still vibrates while
in D at idle - the vibration gets really bad if I have the A/C compressor on.

See above - it didn't make any difference in my case.

You can't simply adjust the idle on these cars, unless you open the
adjusting screw enough to reach the end of the regulating capability of the
ISV, which is definitely not recommended.
