They were sold to me as new, but honestly I have no idea. They don't look machined to me. They are 1 thrust and two others (#1 and #3 I suppose-they are the same) and no rear cap. I bought a set of 5 of these on ebay a few years ago.
As with all caps, the machinist will need to square and bore when installing these.
If you a rebuilding, you probably want this torque plate too.. Make me an offer on everything!
Thanks,
John
