I am the proud new owner of a 1974 PA-28-151 Cherokee Warrior. I noticed that all 3 screws in my pitot blade shroud are rusted as well as those holding my left stabilator tip in place. I will be replacing the stabilator tip with another one in much better shape. I was simply wondering what kind of screws I need for both areas and where I can best order them? This is my first time posting on this forum so thank you for your help and consideration!
