If you have existing F45 Salice hinges you will have no problems fitting there on. The screw holes line up perfectly. I have tall cabinets with each door having 3 hinges. I found that replacing 2 (one at the top and one at the bottom. Left the middle one) works perfectly. When I replaced all 3 the hinges were too strong and the doors would not close on their own.I also have lower cabinets with 2 hinges. I replaced just 1 and it worked perfectly. I would say you don't need to replace all hinges, just some of them.
