^thanks man, thought there had to be some simularities, thats what i was getting at, its not the cup that is worn, its the inner race thats gone, good to hear that 32 etc sare similar parts, i will be looking into this more.
and yea the tripod style cv just looks stronger, ive tried to mix dr30 with hr31 and obviously differnt. but the tripod style is much bigger, has less parts and in hind site just looks stronger.
ive heard mixed results with guys running holden cvs. your probally right thou once its sorted its cheap to fix. but if im gonna spend big $ on cvs. ill be doing it once.
