1970 A Body

I have a 1972 Dart Swinger 2-door.It has the slant six in it now,with the 9 inch drums in the front.I changed the rear end a few years back to a 8 3/4 with 10 inch drums.I,m going to drop in a 1965 383 engine with only 74,000 actual miles.I see you have 10 inch spindles for front.I was just wondering how much more to change to make them fit;since it,s all slant six set up. Thanks.I know i should install 10 inch in front,but i,m not really sure if i would have to.
