First post here. I am having trouble locating the correct throwout bearing and collar for my 84 Brat. I think there was a change that year from 200mm disc to 225mm. It appears that an 84 may have either. That seems to be why I keep getting the wrong bearing for the collar I have. If I get the collar to fit the bearing, it doesn't fit over the nose of the transmission. I need to replace both collar and bearing. Has anyone else ran into this problem? Will I have to order from the dealer to get the correct one, or does somebody out there know where to locate one?
