72 C-10 Steering column brackets

[daniel.wood615]

I'm restoring a 72 C-10. The steering column is not original - probably early eighties. It's loose and sloppy and poorly mounted. I'm replacing the column but I'm fairly sure that the mounting hardware that attach the column to the base of the dashboard is incorrect/missing/rigged. I have searched the usual sources for parts but can't find any source for the hardware and I'm not really sure I know what to look for.

Could anyone advise me of a source for parts or photos of where the column attaches to the base of the dash just below the instrument cluster? I've tried LMC, Brothers, Classic Truck Parts and SOKY.
