Hi Paul.
That thread rod done very little on the T series engine. Even after installing this bar, the engine would rock. And look at how it went! The middle one. This was bolted to lower gearbox to chassis lower cross member:
Bracket on chassis was welded on by Marlin when it went to have the body fitted.
Ended up beefing up the cam side mount stabiliser to the suspension turrent.
As for the driveshafts. These was a problem trying to get these right for the T series. Fix was diesel drive shafts both sides and different mounts to loose the acute angle a bit. Never caused any problems after that.
Saying that. I never heard of any of the VVC guys having any problems.
