i dunno if i'd call reading a 1972 service manual as "up to date experience". i'd really like to know for sure too. books only have words and pictures, and they're drawn and written by second or third hand knowledge by artists and writers, not by mechanics or engineers.
you're talkin' to a guy who's trying to get an s10 rear to fit because it's cheap. i dunno if i can do that either. it's pretty narrow.
