wanted neutral pushbutton for 62 dodge lancer

i need to find out the interchangability on the 63 push button assy. i am being lead to believe that there are many that are the same, only difference is in the buttons. that would be great if i know which are the same. mine has a broken neutral fork that the button goes ionto. i have all of the buttons. but one source that i ran accross said they changed design in 62.
any ideas on interchangability for the 62 lancer assy?
