Thanks for the tip on LUK, I may call them next time. It wasn't my intention to
plug any particular brand or type of clutch with my post but to point out the
pitfalls of buying rebuilt units. I also meant to point out the clutch I bolted
on my 235 is one that fits all small block Chevy's, very easy to find new. Use
the throughout bearing made for cast iron forks rather than the stamped steel
fork.
