At any rate, you'll want to take your car to someone that is very good at what they do. Some cars are not as critical, but Bonnevilles seem to be.

Ive been chasing down the root cause of the shimmy too. Yes it occurs only at the noted speed and beleive me I have tested many speeds... Curiously enough it shows up at slightly different speeds depending on whether I was driving into (shimmied only lower speed) or with the wind (shimmied only at higher speed).
Although I have not had the road force balancing done I have had many balancings and rotations and replaced rotors with no effect. The only thing that appears to have reduced it to some degree is I had a rear left endlink adjustment arm replaced because a mechanic noticed it was a little worn/loose and this appeared to reduce the shimmy by about 50%. I am now wondering whether I should get the other one done too.

You also need force balancing and you need quality, round-rolling tires. You also could have a rim slightly off but that will show on a road force balancer.
My final adjustment came after I told the service manager at the dealership that on a newly-paved I-65 it seemed to do it more pulling slightly uphill on a long grade and didn't show it on the way down. I figured it was front wheel toe-in varying with the pull on the wheels. Rear toe-in was off slightly. The car has Michelin Symmetry tires on it. With miles up to about 15K they seemed to even out and soften in their rolling so the variation was less and less.

just about every time i get a speed(50-70)sensitive shimmy/shake its a dam tie-rod end.
3 times now and each time its one of the tie-rod ends.

There are MANY of us who have experienced this problem, and still do. I feel certain you may have to live with this. I know there are those of us here who will disagree and some will agree. Tires and balancing, and rebalancing, ad infinitum, may not help either. The 2000+ Bonne, especially the SSEi, is known for this anomaly.
It may be a symptom of "cumulative" issues: imperfect tires (non are perfect), light-weight aluminum suspension, light-weight aluminum wheels, imperfect wheels, imperfect tire balance, stiff sport suspensio and on and on.
I'm sorry, I'm afraid I did not notice whether or not you even have the SSEi but Bonne'* and other full-size GM'* are known for this tool. I don't know how to go back and look to see what model you have without destroying this post.......... so I'll post this anyway.
