best place for propshaft and vcu

my dads new freelander has a bad vibration at 60mph so we are going to replace the front propshaft and viscous coupling as they arent in good shape, were is the best place for these parts, would you get a full prop from a breakers with a warranty or is there anywhere better, hoping to just get a full prop so its just a case of unbolting the old and and bolting the new one on, any help much appreciated

Is that definately the problem?

Have you ruled out....

Tyre wear
Wheels out of balance
Drive shafts

Cheers

Have you checked the diameter of the front and rear tyres are the same, difference in diameters cause VCU to prematurely stiffen and causes a vibration at around this speed.
