I had another thought. I might be an ITM or Inland shifter. Don't bother trying to fix it, get a Hurst shifter. First start by torquing the handle bolts, if it has them. Next, torque the shifter mounting bolts, 9/16 and 5/8. Get shifter clip and washer package, Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists , Some O/D A833's had hairpin clips. Next clean, blue loctite, and torque the shift arms to the transmission. I use grade 8 washers and nuts. Use the alignment tool and adjust the linkage rods for Neutral. Only then go into the shifter if that does not tighten it up.
