I had to remove the clutch pedal in my 67 dart. Tried to remove the pedal itself, not enough room to get it out, not even close. I ended up taking everything around it loose and dropping the whole assembly.
There is room to removed the pedals (clutch and/or brake) without removing the entire assembly. Just remember to drop the e-brake assembly (no need to disconnect)...simple pin on the bracket near the handle.
It is an BIG advantage if you understand how the everything comes apart on the assembly beforehand.
