So I finally have my computer back and working so I can post some pics.
These are the original pulleys from a read derailleur along with the pulleys from Bulls Eye, and from Chasertech . Cost of Campy is unobtainium. Cost of Bulls Eye on vintage sites is $50. And the cost of Chaser tech is less than $20 from their web site or on E-bay. You must specify 10 tooth and 5mm to get the diameter right and the correct set of spacers. HTH, smiles, MH

Original pulleys with steel sleeves and bronze bushing material. These are thicker than the replacement parts and only the oil cap goes on either side of the pulleys bushing is 5mm in id

Bulls Eye replacement pulleys 6 mm id and spacer washers to get the right spacing for the chain clearance. The washers are 6mm id

Chaser tech replacement pulleys 7mm bearing id with brass shims for 5mm id. Washers are 5mm to shim out the chain clearance
