Do I need to remove the dash to replace the brake clutch cast iron assembly

The plastic and springs that hold clutch pedal to the truck broke. So can't access this area easily. I'm realizing I'll need to replace the entire clutch and brake pedal and cast iron housing assembly. If I'm correct in thinking this, do I need to take the dash out to do so? What is the easiest way to replace the actual clutch pedal with another? I thought I'd be slick pull the fender out and cut hole big enough to simply replace with a bolt to act as a hinge for the pedal like most models already have. This allowed to much play in the pedal and now can't get it to bleed properly and only goes in gear when car is off. (Yes I already replace the slave cylinder going to clutch pedal through firewall) still won't go into gear.

Brand new clutch was installed when I noticed pedal was broke then I installed new slave cylinder or whatever it's called that goes to the pedal through firewall. So now bought a brake clutch cast iron assembly. I'm just asking if I have to drop the dash in order to install the assembly I now have
