Highway speed vibration and front sounds

Highway speed vibration and front sounds
Morning!
I am about to buy what I think I need of this repair but wanted to ask here first.
My 88 vert will, at highway speed vibrate from what feels like the front of the car. Not all the time but randomly, and more noticeable the faster I go. It's a vibration that resonates through the car and shakes the frame of the windshield if I have the top down. Also, when I go over things like speed bumps, the front absorbers creeeeeeeaaaak as the car bounces up and down and settles. Also, there is a clunk sound sometimes when I do that.
It has gotten worse over time.
What I have done - I have had the wheels rotated and balanced - no change. I have Had my mechanic check the rear suspension and axle and things seem fine. I have changed tire pressure with no change.
I'm being told and thinking it's the front shock absorbers. The creak sound and the clunk are likely from the fact they are completely shot. The bearings have been packed once before but it's been a while but if someone thinks that's it I'm open to suggestions.
I wanted to post here before I spent the money on shock absorbers. Just to get my thoughts out there to a more seasoned audience than me.

Okay. The front and rear struts are replaced and bushings as well.
It vibrates WAY less but still, then I hit w bump, the caR shimmeys a bit more than it should and the vibration is still present, just much less.
I'm assuming control arm bushings next?

jack the car up and rock the wheels back and forth to see if they are wiggling around on the spindle.
If you go for an alignment, they'll check this.
If it does in fact wiggle on the spindle, bad wheel bearings.

Update.
Tire place replaced two rear tires for flat spots. So I have new struts all around and two new tires. The vibration is much better. No alignment because the tires showed no tread signs of it being needed.
However I have noticed that when I hit bumps it tends to shake up the frame and the struts don't absorb it as much. This may be normal but I've had bad suspension for so long I can't be sure. Also over a speed bump I hear a creak as the car goes up and down. I did some reading and it sounds like control arm bushings could cause that.
Maybe my control arms and bushings need replaced too?

Doesn't matter if the tires don't show bad tread wear. Get the alignment done. After replacing your shocks it has to be done. You can't take the system apart and put it back together and not mess it up. BUT if you plan to do all your bushing do the alignment after replacing them.
