1968 6 Cylinder Radiator Hoses Part Numbers

[stovebolt]

I'm looking for the GM part numbers for both radiator hoses for my 1968 6 cylinder engine? No P/S, no A/C, no A.I.R. Also, does anyone know of a source (besides GM dealers) where I might find both? Thanks for your help. Joe.

The upper was 3905964, and the lower was 3891554. NPD has the lower, but not the upper.
