Help - Rear droplink nightmare

[melvin]

I've been needing to change the rear drop links and finally started it today.
Had no problem getting the old droplink off the anti roll bar, but having real difficulty with the torx bolt.
Its really tight, i rounded the inner torx, tried vice grips on the outside of the bolt, still cant shift it.
Any ideas?
I'm probably going to have to get a replacement bolt when i do eventually get it off!
Have dropped the lower control arm and removed coil spring for better access.

Lots of heat and stilsons.

I went at it again this morning. Didnt have any access to heating eqpt. Finally got it to move with the vice grips and a bit of pipe on for leverage. It was tight all the way out. Still got other side to do, but i need to pick up a coil spring first as its broken.
