Upon closer inspection I find I have a modified oil pump and I think Packard did it. That means there are three different oil pumps. 
1.The pump used in 1955 and part of 56 which has the relief valve spring contained by a small cup and a cotter pin.
2. A pump which still bears the same casting number 440662, but was never drilled for a cotter pin. The casting is threaded for a bolt with a gasket on it. Packard must have been using up the earlier castings but modifying them for a sealed fit at the pressure relief port. I can't blame Packard for not wanting to scrap a bunch of castings.
3. The modified pump mentioned in TSB 56T-20 which has the casting number 64xxxxx. Actually they could be referring to pump number 2 because it has the threaded plug.
In any case I called on Packard Parts Extraordinaire and he is sending down the latest oil pump which I intend to have Bob Aller rebuild.
