what shifter are the stick people using

I am installing the v gate I have had for years. With the 4 speed hump in a duster is there much trimming that needs to be done?

The V-gate, which I like extremely well, was one of the luxuries included in the purchase of my Barracuda. Unfortunately it did need some mods to the tunnel hump. Some of the mods went a bit overboard I believe, but hey, Big Bill was not a little guy.
In the pictures you can see the hump hole has been modified in all directions. Some of it cut out of the front and passenger sides and the flange folded down in the rear and driver side. The vertical areas have not been altered.
You can see how close things are underneath in the crappy picture. Also note the cross member had been notched and one bolt shortened.
I feel if fitted from the top and taking your time some of these alterations could be minimized.
Hope these help,
