I've done a number searches and looked at various sites, with no luck....can anyone suggest a good site/source for a new Shimano bb-6503 english thread octalink bottom bracket. I just learned the difference between Octalink v1 and v2. I don't think I destroyed my crank

The Ultegra-level (BB6500 and BB6503) Octalink bottom brackets, both double and triple, have been discontinued so you have to luck into one NOS somewhere. None of the common mail order places have them anymore.

The 105 level equivalent bb (BB5500 and BB-5503) are still in production and are good replacements. Licktons has them. Here is Lickton's URL for the BB5503 triple version:
