[Vwdiesel] Quantum steering removal

[mark shepherd]

On the rack of a manual Steering Quantum there are 2 allen headed bolts that hold the end of the rack firmly onto the wheel arch. I'm finding these are severely corroded.  I've removed the  locking nuts in the engine compartment but the bolts are stuck. Do the bolts screw into the rack, or is it just rust?
I may hammer a torx into the holes... I'm just salvaging the rack from a dead Quantum ...
Thanks
MarkPS does any one know where I can get an old style European 'KATE' Mine is North American and limited in Quantum stuff.
