there was a bit of nice process in the anime where Ranma was in the rain and Happosai gropes him right after the change where you see the breasts grow in full view. cant remember the name of the epidsode it was one of the stories from the manga where the put girl repellent on his Hapo's back.

but I have most of the show on dvd and a lot of it is Poof or wacky slide panel. but they had less to work with in the 80s.
