663H available everywhere here easy as pie--The mains can be replaced with any "H" style to work with aftermarket cranks most here use the MS909-H again..easy as pie to get
Many have switched to King HP series--they work great as well and are less expensive than Clevites
Any of these are available from any parts seller --Good Luck!

  GasserX:
 The CB663H was a hard coat bearing with a chamfer on the outer side of the bearing to match the rod.
The same bearing is now CB663HN. Same bearing just narrow or not as wide.
Gives you the same bearing surface but was cheaper for them to make.
The Federal/Mogul or Speed-Pro bearing still have a wide body with a chamfer.
Part number 8-7100CH or 8-7100CHA with a dowel hole for aluminum rods.
