I had to relocate the hole in the tunnel to accommodate the Hurst shifter. But my car didn't have a properly located shifter hole/hump to begin with since it was converted from an Automatic. So I located it by dimensions provided by others. Then, adding the Hurst shifter, I had to cut the hump on the driver's side to set the body on the frame. It works fine.
I also bought the adapter to use the Muncie shift handle with the Hurst shifter. But after reports of dissatisfaction with the height of the shift handle and ball, I took Brian's advice and bought the Hurst-compatible handle from Lutty's.
So, if anyone needs an adapter for the Muncie shift handle on the Hurst shifter, I have one available.
