The original Hurst Super Shifter 1 which was released circa 1971/72 was nothing more than a Hurst Competion Plus Body that was mounted high up off the transmission tailhousing and used a short 7” straight bolt on handle. This Super shifter 1 used a flat plate bracket and 3 solid spacers & grade 8 bolts. It used straight rods with a length of tubing over them, and conventional Hurst tags/swivels/bushings & clips. The tubing was crimped in the middle for retention. This 1st design Super Shifter did not use a push down for reverse and it said Hurst Competion Plus on it.
The Super Shifter 2 released approx 1974/75 ? was redesigned to fix issues with the bracket coming loose on tailhousing after repeated slamming of gears, and it used a redesigned mounting bracket that consisted of a piece of channel welded to the flat plate that eliminated the spacers. The shifter body said Super Shifter on it and was redesigned with push down reverse lockout function and had a small coil type spring located at the front on the bottom of the shifter body, this Super Shifter 2 also used 1-2/3-4 shift rods with crimped tubing. It had a tendency to pull the reverse lever slightly when slamming 3rd gear and you had to absolutely make sure the stops were set perfect or it tried to move the reverse rod ( causing grinding ) probably due to the spring causing load or friction between the internal body 3/4 & reverse levers.
The Super Shifter 3 used redesigned rods that were threaded where the clips go and used thin nylon type crimp nuts & wave spring washers and the body was redesigned and it no longer used the push down reverse function, it used the red handle positive reverse lockout , no idea the release date on it. It used a similar bracket as the Super Shifter 2, but stronger design.
Graeme you will have to cut a small horizontal notch in tunnel approx 4-6” long for the 3/4 rod as it leaves shifter body towards tag, you will also have to notch the tunnel somewhat for the shifter body and bracket . You can tweak/bend/pry the side of the tunnel somewhat to clearance for the 3-4 rod as it approaches the side cover tag. We just used to let the carpet cover this small slot. Keep the piece you cut out of tunnel, it can be welded back in if you ever decide to go back to original.
Hope this helps. Best of luck.
