How to find out what style of shifter is in 3 speed with overdrive on the floor

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.
Would that tighten up the shifter itself at the moment it has a lot of play in each gear, and when you say get a hurst shifter do you mean get the entire assembly I know that on the arm itself it says hurst.
