Topic: Changeover from C5AE to C5OE single groove water pump pulley?

[CharlesTurner]

Does anyone know an approximate assembly line period of when the single groove water pump pulley's were switched from the C5AE to the C5OE?  Reason was due to chaffing of the belt on the pulley for p/s equipped cars.

Don't recall it being in the TSB's I've got and the first one in that series was printed on Oct 19,1964 so might before that but that is a long shot.

Sure you've already looked in a 65 or 64 MPC.

Don't think I could tell the difference from just looking at them or would check the pictures for additional data
