Hurst pit pack doesn't fit hurst shifter!?

You might need to make your own bushings or find ones that fit if you have an old one that is good enough to match up. I had this same problem with the 4 speed in my 65 Barracuda years ago but luckily I had some decent used ones so I just used the clips from the kit.I think that kit is for more modern cars.What year is the transmission ?
