Ok so some people say when swapping cams without removing the front chain cover the AFM retention tools works wonders. Some say it sucks and to buy the ford one. But I keep getting a 50/50 result when viewing old posts. Wich tool do you guys think is the best? Are they made of plastic or metal? Plastic seems like a bad idea because of risking dropping broken pieces down in the cover. What is the part number for the ford tool? The Anderson one is like 30 bucks.
