the straight shifter handle was supplied by GMM with the ripshift after I described what I needed on the phone, they had one still there from a batch they had in stock previously. I think it might be the same top handle the corvette setups use but don't quote me on it. There is none of the VT-Z shifter involved except the VY SS gear knob and boot (which I'm still not sure how to get integrated into a VN centre console)
