Nude Shifter pics , which one ?

[usa-69z]

I have here an aussie Ls1 tremec T56 6 speed that needs a shifter. I have looked at most shifter pics (aftermarket ) but they dont look like they have the same size bottom plate which holds shifter to box. These boxes are in the GM Ls1 commodore 2002 model and have the shifter set way back behind the housing.
Can any-one recomend a shifter that will bolt on that will bring it foward as much as possible ? Its going into a Right Hand Drive 69 camaro without a console .
any help is appreciatted .
