You have a Supershifter 2. Later it became the Street Supershifter. That is a street shifter, that doesn't require any modification to mount. The rods are straight for forward gears, but they are not horizontal like a Supershifter. To install a Supershifter, which is a race shifter, you must cut the back of the hump off and remove it so you can mount the large "L" shaped bracket that the shifter mounts on. This raises the shifter up and INTO the interior of the car. This allows the rods to not only be straight, but they are completely horizontal as well. These shifters have the levers that the rods attach to all the same length. I have a 33 year old Hurst catalog in my hands, and it shows the street version. The difference between the Supershifter 2 and the comp+ is the Supershifter 2 ( like the original race Supershifter) has further heat treated parts with reinforced rods, built in reverse lockout (unlike the old Supershifter), and a narrower neutral gate for easier/faster 2nd/3rd shifts.
