Adjustable 34mm scope rings

[Tenebris]

Hey guys,
Does anyone know where I can obtain some 34mm Weaver style scope rings that are adjustable for windage? I'm mounting an S&B on an F Class rifle and the horizontal alignment is slightly out and I run out of windage adjustment. I believe that the rail is the problem but I need adjustable scope rings to correct the problem. I don't want to use any shims as these could damage the scope.
Any suggestions would certainly be welcome!

Stupid question... why not just replace the rail ? Given the money invested in scope and rifle, seems strange to go to a less-than-idea ring when the rail is what is causing you grief.
