Steering shock stabilizer bushings missing and shock is leaking, what type / part numbers are needed to replace front stabilizer bar and or bushings are

What is your question?

Entire front end of LandRover is vibrating when going over 45 mph- & when driving on rough road patches , can feel in steering wheel . Mechanic states steering shock stabilizer bushings are missing & shock is leaking - need to remove & replace front stabilizer bar & or bushings. 2nd issue- Traction bar bushing is bad causing front end to shift left and right - must remove & replace front torsion rod. LandRover no longer carries repair parts for 1997 LandRover Discovery- do you know compatible parts I can purchase from on line with stock number ? Many thanks .

Uneven concrete on road & 45 mph plus
