I believe that Marlins short throw shifter kit will give the hieght you are looking for and shorten the throw all in one. Look into it
I could take it out, cut and weld it but i was thinking if i could find something to thread over the shift knob part that will extend it like and inch or two.
And 84runner i thinkt he short throw is only for the t-cases...I wish they made one for the tranny
