Hurst street super shifter

do you mean that there isn't enough adjustment on the threaded end of the rod? Did you put it in neutral with the 1/4" pin in the shifter 1-2, 3-4 levers? disconnect the reverse lever at shifter, and see if that helps locating all the forward gears.
When I put the lever opposite of the hurst diagram I cant get it bent with enough length on the threaded end, it gets hung up on the crossmember
