Thanks for the responses guys. Sorry for the confusion on naming convention. I am talking about the 33 mm fork tubes that extend through the triple clamps.
I've found a pair of NOS tubes at $190 each that I'm reluctant to purchase without considering alternatives. I'm thinking that cosmetic plating might be a bit cheaper but may not be work because the final OD isn't a controlled parameter. Its all about appearance. On the other hand, precision OD grinding and hard chrome are probably more expensive than buying the NOS parts.=
