I think that we can generalize and say that most all the parts available 
these days off the shelf suck. I'm replacing the clutch in my wife's daily 
driver TR6 because the new throwout bearing carrier I purchased and mounted 
with a Toyo bearing couldn't take the wear from the hardened steel locating 
pins on the new fork.  I put new parts in just so I wouldn't have to revisit 
the job. The pins wore notches into the slot on the carrier. I'm a little 
more than peeved.
