chevelle and skylark questions

i was wondering if chevelle control arms both upper and lower will fit a buick skylark? if so, are the ball joints and bushings the same? any mods needed? would be a big help guys, thanks

 

front arms interchange 64-72 , rear has differant lengths on top 64-67 , 68-72 etc.
the rear bushings interchange from 64-81. Front tops bushings are same but there are differant bottom bushings on lowers, oval or round, as long as you have matching on both sides its fine, can get bushings for both . ball joints interchange ffom 64-72 maybe newer

 

thanks alot, helps alot man
