Bill -- checked a couple of my mid-60s P&A30's.

Gr 16.603 is Panel, Reinforcement, Extension plate, Pad, [for front door sill]

But all listed numbers (none show the 6-digit series you report) are for G-10 and series 10-20 Panel and Pickup trucks.

If you've got a 73-77 Chevrolet Blazer, then you've got some spare parts for it. GM #339909 and GM #339910 are the left and right side rear sill plates.
