Finishing up on the Willys. I'm running a set of modified Cherokee pedals that I got from @ghost. There is a considerable amount of slop(L to R 1/2" or so) when you depress each pedal. I have reinforced the firewall with 1/4" plate as well so I know the firewall is not flexing. I have also added plate to the pedal assembly to make sure its not bending etc. Should I get new bushings for these pedals or just go straight to Wilwood pedals? I have a limited area to work in so size is a consideration.
 
Personally since it's already there I'd try new bushings first.

Bushings replaced. It took all the slop out but still have issues. Even with the 1/4” plate on the firewall it’s still binding the pedal assembly when the clutch is depressed. Instead of operating in a linear motion, the pedal is acting in an inward arc which binds the pedals and assembly together. I assume because the pedal arm is offset from the clutch slave about 1.5”. I just ordered a single wilwood clutch pedal that should be here on Thursday

Those arms flex and bend believe it or not. I had an issue with my xj slave not working. We cut the pedal and bent it up and re-welded it together. Basically gave me more throw of the pedal. Come to find out the slave section was twisting and loosing throw. I welded a plate between the pedal and the throw and it stopped flexing and worked right.
 
@ghost I reinforced the pedal assembly with some plate and added some 1/4” plate to the firewall to stiffen everything up. I even cut and RE welded the pedal arms and still got a lot of play. Still got a lot of flex in the pedal assembly when the pedal is depressed. Hopefully the new clutch pedal I have ordered will correct this.

When you get it out I'd love to see pictures of what you did. My visual mind is not seeing it. I'm talking about tying the pedal to the throw arm.

The clutch arm/pedal is about 1.5” offset from the slave cylinder. So instead of force being applied directly to the slave cylinder, it’s forced at an angle which is probably multiplied by the flex in pedal assembly.

I know it’s flex in the assembly as the slave/master does not move at all when the pedals are depressed. I can also view the pedal assembly flexing under pressure.
 
I ordered the Wilwood 340-13834 pedal off Amazon yesterday, should be here by tomorrow.
 
New pedal installed and its amazing. Well built and easy to install. Completely fixed my clutch issue.
