1985 300sd side to side shake (kind of loping) at idle when warm.

Well, I bought the 85 30sd I went to look at 280miles away. I was drooling when I saw the $2600 receipt for a recent "tune up" from a local mechanic which included all new hoses(even transmission cooler), belts, waterpump, and almost complete front end rebuild. The paint sucks, but cant be too choosey...
Anyway, I could tell that the man always babied it and he admitted to never driving over 60-65mph, well the first time I took her to WOT I lost sight of my civic that a friend was following me with on an on ramp. It poured black smoke. After a few rounds of that and 75-80mph driving for 5hrs, she doesnt smoke. BUT, she shakes really bad. And by shake, I mean the whole care moves side to side slowly, almost like extreme loping. Only at idle, and if I pick the idle up to 800-900 it goes away.
After some searches I decided the issue may be worn out engine damper shocks, so I went out to look at them. NEITHER ONE WAS THERE! Completely gone, just empty holes for where they mount. So Im alittle pissed I didnt see this when I was looking at the car, bc now I have to spend another $250+...
Also, am I correct in that a 85 300sd should have a 120mph speedo, bc this one has an 85 like out of an 81-82?? Need to replace that soon, drives me nuts to be doing 65, and looking down and thinking im doing 100mph at first glance.
