Default Ford Granada driveline vibeation

Hello guys, this is not really an performance ford but I hope you can point me in the right direction.

My 81 Granada 2.3 4 speed with 76.000km vibrates while driving past 50mph.
I tought it was the rubber in the middle of the propshaft, checked it, had some play so I changed it. Now it's even worse, maybe because I stiffened that part up. U-joints are good. When I took the propshaft away from the car I marked it's position to be sure it would go back as it was.

Where to look?

Have you tried swapping the wheels front to rear to see if the vibration changes?

Inner CVs used to get dry and require regreasing

Other than that propshaft balance weights may have come off?

wheel balance/ out of shape tyres.

Weight is still in place, tires are new and balanced. CV joints haven't been checked. Will do. Thanks.

I would start at the engine mounts and replace everything working back, these cars are so simple that it cannot take a lot to change everything, eventually you will resolve it.

And did this just start suddenly, or after work ? Other ?

And it is definitely speed related, not engine rpm etc ?

Swapping wheels or tyres would be a good first step
