1952 3800 Upper Steering box bearing.

[ChevyBrad]

Does anyone know where I can get the upper bearing for my steering shaft in the top of the column. I am modifying the original column using U-Joints to clearing the box for my V8 swap and if I could find two more bearings I could use them at the top of the box and the bottom of the column at the firewall. It looks like it is recessed enough to allow a shaft seal to be pressed into the inside of the bore creating an environmental seal. Any thoughts? Thanks.
