Sounds like another case of incorrect pinion angle causing a driveline vibration. Is the car lowered?
Hmm with it being at 150k miles your bushings shouldn't be worn to the point of them causing the vibration. And you've got new brakes and rotors and etc...
Alright try this: push on the rear of your car, just not on the spoiler, and see if it dips down a lot and count how many times it bounces before settling.

I probably should explain myself 
I bought my car with Monroe SensaTracs only on the rear with stock shocks in the front 2 years ago and it shook horrible from 65-73ish. I still don't know how many miles were on the shocks but I could not figure out why my car shook so bad. After throwing a little money at it, I replaced my rear shocks and my vibration was no more.
I replaced my rear sway bar, rear lower control arms, panhard bar, tie rods, and gave my car a tune-up and still my car vibrated horrible. Again I'm not saying it's your problem, but it'll give you something to think about.

I might try that. what shocks did you get? should I get new bushings or look for anything else while doing the shocks? I am so tired of dealing with this. many have drove or rode in my car and not a clue to the cause. two of them ase certified mechanics, both of them said road force balance. I have done the road force balance, still there. I still love to drive my car, but this vibration does take a lot of the fun out of it

I know exactly what you mean. I drove my car for fun in the summer but the highways sucked when it would vibrate. The best feeling is finally fixing it and having it finally driving smooth.
I got KYB gas-a-justs. They're alright with a "jarring" type of feel to them when I go over bumps, if you have the money I'd shoot for some Bilsteins. Replacement is fairly easy, not a whole lot to check out in the rear except to make sure everything is bolted up tight, check your sway bar end links, they're right there by the shocks.
Hope this helps
