89 ford f150, housing for brake and clutch pedal broken. How hard to replace?

 

You are on the wrong Community for an answer to this one. Go to the Pre-97 F150 Community at this link: https://www.f150forum.com/f9/

It might also help if you can elaborate on what you mean by "housing" on that site. Are you talking about the clutch and brake pedal assembly?

Good luck and welcome to 150s!
