Fix your linkage and quit "Hacking"! Nothing worse than a floor shifter that don't work right and you have to bend over to reach or make a longer lever and have way long throws with it. You can rebuild the shift box on column under firewall and put new bushings in the link holes, using new brand bushings. Hurst will have those. It won't shift like a "Racer" either, unless you use a more modern trans, and that would require a new rear-end and driveshaft as you now have Torque-tube one-pc rear.
Can you tell I hate changing from stock? :p :p :p
