I have it on my Coronet I converted from column shift auto to a console 4 speed. I have a 23 spline trans but it's the same thing. I love it, effortless shifting nice and smooth. Frankly the main reason I went with the hydraulic throw out bearing was because I didn't want to deal with rounding up all the linkage and welding the z-bar plate to the frame but either way it's a great system and works as well as or better than the factory mechanical linkage. No more over center spring on the pedal either.
There are a couple things to be aware of since this is a universal kit that has been adapted for Chrysler applications. For example, the firewall support plate and clutch rod can be a bit of a hassle. In theory you want the clutch rod installed with the right pedal ratio. The factory clutch rod knob thing on the pedal is in the right spot for that but unfortunately it's too big for the heim joint arrangement they give you. Didn't realize that little tidbit until the pedal was in the car and I was installing the rod. Doh!
So rather than taking the entire pedal assembly out again to get rid of the pedal knob, I cut down an original clutch rod then drilled and tapped the cut end for the threaded rod and adapter they give you. The OE clutch rod is angled toward the steering column which is why they give you the heim joint to account for the angle. I did have to grind out the firewall plate because it was interfering with the full travel of the rod but it wasn't a big deal and it all works great. Might not have to do that if you just use what they give you.
Don't let any of this scare you away from it, just plan it out before you start drilling holes and it will be fine.
