Yep, $60, which is probably more than the RD. I was thinking in shorthand... I sent my spacing kit to the lady in Brooklyn (whatwolf)... I believe it's on her Merckx, not sure.....
They're to mate a Shimano 8/9/10 rear hub to a Campy drivetrain. I think the OP was trying to make a Campy shifter work with a Shimano RD....
anixi seems to have found a solution, but I'd still just get the RD to match the shifters and call it a day.
