Hey snoopy13, Finding the right hands can be a challenge. It is difficult to answer your question not knowing what type of clock or hands you are dealing with, or where you are already buying them from. Yes, sometimes you do have to perform some modifications to make them work. For myself, finding and buying the right hands for French clocks can be most challenging. Are you able to post some photos with some information about where you bought them and the problems you are having?
