The Hurst "Ram-4" looks like it would work but I tried to race one with a slicked up Hemi box and I prefer the Super Shifter III or a Long V-gate .
My favorite was Long V-gate and Heim joint linkage.
I purchased my tubing from Liberty Gears and the heims from Long.
I also used a Long V-gate on my Richmond with Face-plate gears from Liberty and it was so much fun to do full throttle power shifts never missing a gear.
Spend the money on a Long shifter for a V-gate or look for a NASCAR Hurst shifter or "good used" Super Shifter III if you want an "H" pattern deal
