Tom,

In the 55 - 56 Parts and Accessories List, available for download from PackardInfo, under Group 3 in the Clutch and Transmission section see Page 36 under 3.510 are listed P/N G179862 All 55th; 56th Screw 7/16"-14 X 1&1/2" - 9 off and P/N 470058 All 55th; 56th Screw 7/16"-14 X 1&11/16" - 1 off. They would be UNC. I think these are what you need but not being a V8 guy I'd wait for confirmation from the V8 guru's.
