I don't think that I have one anymore ... however its not that much or that complicated. I suggest installing the shifter and then look at the spring on the side. You will see where its making contact and will not let it shift. IIRC the piece that needs to be removed is only 1/4 x 1/4 inch. You just need to remove enough metal on the side of the shift tower to allow full movement of the shifter spring.
I'll try to take a photo of it when I get home.
